    ABSTRACT: There is a rich tradition of writings about the foundation of psychology laboratories, particularly in the United States and in France. Like their German counterparts, American laboratories of psychology were described by several scholars in French journals. These descriptions stimulated the establishment of laboratories in France and provided templates for laboratory designs. We introduce here an article written by Marcel Baudouin (1860–1941), who visited and subsequently described the psychology laboratory of Granville Stanley Hall (1844–1924) at Clark University in Worcester, Massachusetts. The English translation of Baudouin’s paper, provided here, constitutes an interesting new document on Hall’s laboratory at Clark University as it stood in 1893. From the French perspective, the Clark laboratory provided an ideal model for the experimental psychology laboratory.

    ABSTRACT: College students searched for either h or the in prose passages in which every h occurred in the test word the. In Experiment 1, passage versions differed in that the critical noun phrases were either the alone (i.e., in citation form as a noun referring to itself) or "the definite article." Many more detection errors occurred for letter than word target items, especially with "the definite article." In Experiment 2, passage versions differed in that a given noun phrase containing the test word the occurred as a subject in one version and an object in the other. Again, many more detection errors occurred when the target item was the letter h than when it was the letter sequence the. Also, with letter but not letter sequence targets, more detection errors occurred for object than subject noun phrases. In Experiment 3, passages were presented either in regular format or with all capital letters. Students made more detection errors with the regular than with the capitals format, many more errors occurred when participants searched for letters than for letter sequences, and the effect of target item was larger with regular than with capitals format. These findings suggest that accounts of detection errors in reading must include the influence of unitization and processing time or attentional allocation.

    ABSTRACT: First-year undergraduates participated in a short-term longitudinal study of goal setting and decision making over their first 14 months of college. First, students wrote a mission statement, listed their goals for the upcoming year, and filled out several individual difference style measures. In subsequent sessions, students were surveyed about different decisions pertaining to their choice of college major, course selection, housing, and summer plans. At the beginning of their second year, participants were shown their previously listed goals and surveyed about their progress, their satisfaction with their progress, and their retrospective view of their goals. Additionally, participants responded again to the individual difference measures. A moderate degree of stability was found in the individual difference measures, yet there were several significant changes over the year. Goal evaluation scores correlated with specific individual difference measures, and self-reported descriptions of reactions to how specific decisions were made, but not with behavioral measures of decision making.We speculate on ways in which stylistic measures become part of a construction of a more general narrative identity, shaped in significant ways by the college environment that selectively reinforces some analytic habits of mind.

    ABSTRACT: Perception of affordances for a given behavior reflects not only a person's current action capabilities but also impending changes to his or her action capabilities. This experiment investigated perception of affordances for reaching when the means of performing the reaching task would increase or decrease reaching ability. The results showed that in both cases perception of maximum reaching height reflected the person's anthropometric properties (i.e., standing height) and the future means of reaching, and improvements in perception of maximum reaching height transferred to unpracticed reaching tasks. The results highlight the role of action in the perception of affordances and are discussed in the context of a description of perceptual systems as smart perceptual devices.

    ABSTRACT: Participants who evaluated 2 positively valued items separately reported more positive attraction (using affective and monetary measures) than those who evaluated the same two items as a unit. In Experiments 1-3, this separate/unitary evaluation effect was obtained when participants evaluated products that they were purchasing for a friend. Similar findings were obtained in Experiments 4 and 5 when we considered the amount participants were willing to spend to purchase insurance for items that they currently owned. The averaging/summation model was contrasted with several theoretical perspectives and implicated averaging and summation integration processes in how items are evaluated. The procedural and theoretical similarities and differences between this work and related research on unpacking, comparison processes, public goods, and price bundling are discussed. Overall, the results support the operation of integration processes and contribute to an understanding of how these processes influence the evaluation and valuation of private goods.

    ABSTRACT: Mental rotation is one of the main spatial abilities necessary in the spatial transformation of mental images and the manipulation of spatial parameters. Researchers have shown that mental rotation abilities differ between populations depending on several variables. This study uses a mental rotation task to investigate effects of several factors on the spatial abilities of 277 volunteers. The results demonstrate that high and low imagers performed equally well on this tasks. Athletes outperformed nonathletes regardless of their discipline, and athletes with greater expertise outperformed those with less experience. The results replicate the previously reported finding that men exhibit better spatial abilities than women. However, with high amounts of practice, the women in the current study were able to perform as well as men.

    ABSTRACT: Individuals vary in their propensity to engage in aggressive behaviors, and recent research has sought to identify individual differences that contribute to a person's propensity for physical aggression. Previous research has shown that impulsivity and aggression have a consistent relational pattern among many different samples. However, not all impulsive people will engage in aggressive behavior, perhaps because of other factors such as level of physiological arousal from anxiety. Specifically, one factor, namely physiological symptoms of anxiety such as those often associated with panic, may help as a predictor variable to be used in risk assessments or subclassification systems of aggression. Participants included 689 college students who completed self-report questionnaires assessing impulsivity, physical aggression, and anxiety. Multivariate hierarchical regression analyses were conducted. Greater scores on the measure of impulsivity were associated with higher levels of reported physical aggression. The interaction (impulsivity x anxiety) was not statistically significant, suggesting that impulsivity has the same effect on physical aggression regardless of the level of anxiety. There was a main effect for anxiety, which was associated with higher levels of reported physical aggression. Our findings may help inform typologies for identifying predictor variables used in risk assessment and treatment planning.

    ABSTRACT: In lucid dreams the dreamer is aware that he or she is dreaming. Although such dreams are not that uncommon, many aspects of lucid dream phenomenology are still unclear. An online survey was conducted to gather data about lucid dream origination, duration, active or passive participation in the dream, planned actions for lucid dreams, and other phenomenological aspects. Among the 684 respondents who filled out the questionnaire, there were 571 lucid dreamers (83.5%). According to their reports, lucid dreams most often originate spontaneously in adolescence. The average lucid dream duration is about 14 minutes. Lucid dreamers are likely to be active in their lucid dreams and plan to accomplish different actions (e.g., flying, talking with dream characters, or having sex), yet they are not always able to remember or successfully execute their intentions (most often because of awakening or hindrances in the dream environment). The frequency of lucid dream experience was the strongest predictor of lucid dream phenomenology, but some differences were also observed in relation to age, gender, or whether the person is a natural or self-trained lucid dreamer. The findings are discussed in light of lucid dream research, and suggestions for future studies are provided.

    ABSTRACT: Findings in a number of neuropsychological studies involving reports of decisions to initiate spontaneous movement (e.g., Fried, Mukamel, & Kreiman, 2011; Libet, Gleason, Wright, & Pearl, 1983; Soon, Brass, Heinze, & Haynes, 2008) are often interpreted as putting in question the reality of conscious control and, by extension, the time-honored concept of free will. I suggest that several problems with the basic paradigm used by most such studies, elaborated on in some recent articles (prominently Miller, Shepherdson, & Trevena, 2011, and Schurger, Sitt, & Dehaene, 2012), as well as some other arguments, raise doubt that conscious control is in fact a gratuitous byproduct of preconscious brain activity.

    ABSTRACT: These studies examined memory encoding to determine whether the mere exposure effect could be categorized as a form of conceptual or perceptual implicit priming and, if it was not conceptual or perceptual, whether cardiovascular psychophysiology could reveal its nature. Experiment 1 examined the effects of study phase level of processing on recognition, the mere exposure effect, and word identification implicit priming. Deep relative to shallow processing improved recognition but did not influence the mere exposure effect for nonwords or word identification implicit priming for words. Experiments 2 and 3 examined the effect of study-test changes in font and orientation, respectively, on the mere exposure effect and word identification implicit priming. Different study-test font and orientation reduced word identification implicit priming but had no influence on the mere exposure effect. Experiments 4 and 5 developed and used, respectively, a cardiovascular psychophysiological implicit priming paradigm to examine whether stimulus-specific cardiovascular reactivity at study predicted the mere exposure effect at test. Blood volume pulse change at study was significantly greater for nonwords that were later preferred than for nonwords that were not preferred at test. There was no difference in blood volume pulse change for words at study that were later either identified or not identified at test. Fluency effects, at encoding or retrieval, are an unlikely explanation for these behavioral and cardiovascular findings. The relation of blood volume pulse to affect suggests that an affective process that is not conceptual or perceptual contributes to the mere exposure effect.

    ABSTRACT: The present studies used exploratory and confirmatory factor analyses to explore the degree to which probability discounting processes are similar to delay discounting processes. To determine whether these processes are similar, 2 questions were addressed: the degree to which probability discounting outcomes can be categorized into multiple domains (as demonstrated for delay discounting) and whether the inverse magnitude effect would be observed for nonmonetary outcomes. An exploratory factor analysis was conducted using data from the fill-in-the-blank method (Study 1), followed by a confirmatory factor analysis using data from a multiple-choice method (Study 2) as a replication. These studies provide support for the idea that outcomes can be subdivided into multiple domains. Generally, the discounting rates were steeper for tangible outcomes than nontangible outcomes, and a magnitude effect was observed that was consistent with, rather than the inverse of, that observed for delay discounting tasks. Complexities related to the relationship between probability discounting processes and delay discounting processing are discussed.

    ABSTRACT: A recent meta-analysis showed a robust gender difference in nightmare frequency of medium effect size in adolescents and young adults: Women tend to report nightmares more frequently than men. The present study, carried out in an unselected student sample, indicates that 2 factors mediate the gender difference in nightmare frequency: neuroticism and overall dream recall frequency. The effect of neuroticism on the gender difference and the finding that the gender difference in nightmare frequency emerges at an age of about 10 years suggest that gender-specific socialization processes may play an important role in explaining the gender differences in nightmare frequency in adolescents and young to middle-aged adults. This idea is supported by the previous finding that nightmare frequency is related to sex role orientation. However, longitudinal studies are necessary to validate these hypotheses.
