Biological functions, such as deep body temperature, vary rhythmically throughout the day and in synchrony with the individual's chronotype. The same happens with cognitive functions such as attention, or memory. While participants performed the encoding phase of a memory task, the ECG was recorded with the objective of examining the effect of the...

Sexual dimorphism, which corresponds to the phenotypic difference between males and female from the same species, is one of the main factors that was proven to influence facial attractiveness in humans. Although there are several studies about the impact of sexual dimorphism perception in mate choice, the underlying neurophysiological mechanisms ar...

The influence of the synchrony effect (congruence between chronotype and time-of-day) on the mnesic and attentional performance is well documented. However, studies that relate the synchrony effect with identification performance on lineups are few and focused on recognition. Thirty-four participants watched eight theft videos, each followed by an...

Errors in eyewitness testimony are frequent and problematic, due to the ethical and social impact of false positives. As an attempt to reduce the number of errors, it has been suggested that identification markers based on methodologies like ERPs should be developed. Twenty-nine participants viewed crime videos, each followed by an interference tas...

A recent study claimed face skin color as a sexually dimorphic variable that influences attractiveness preferences in mate choice. Thereby, skin color may assume the role of a mate quality signal influencing attractiveness preferences. As body odor is linked to attractiveness, this study aimed to explore whether the odors of men with more masculine...

Research investigating the effect of lighting and viewpoint changes on unfamiliar and newly learnt faces has revealed that such recognition is highly image dependent and that changes in either of these leads to poor recognition accuracy. Three experiments are reported to extend these findings by examining the effect of apparent age on the recogniti...

Body odours may possess an inherent higher level of relevance to the perceiver by assuming an evolutionary function of promoting one´s genes. It has been demonstrated that olfactory signals with high ecological importance, similarly to visual signals, are processed in a privileged way by the brain. Body odours of more masculine men might trigger hi...
Article
Evidence for attraction to sexually dimorphic features in male faces is inconsistent in the literature. Mixed results regarding facial masculinity and male attractiveness may arise partly from different influences of face shape and face colouration depending on whether colour was controlled. Recent research suggests that masculinity in face colour,...

The environment presents a multitude of relevant emotional stimuli to every sensory modality. Although communication is typically multimodal, vision and audition are considered the primary sensory modalities, while olfaction is often neglected. The communication of emotions, like fear, can be enhanced if stimuli are presented in different sensory m...

In crimes committed under unavailable visual cues, the earwitness testimony might be the only available evidence. Several factors have been considered to investigate the possible application of this evidence in criminal context. However, the majority of the studies report relatively low accuracy in earwitness identifications. This study aimed to ex...

Some studies have found that higher masculinity is attractive when females assess male faces but others found a preference for feminine features. It has been argued that these mixed results regarding masculinity and male attractiveness may have been due to differential influences from shape and colour information. According to this view, masculinit...

It has been suggested that familiar and unfamiliar faces employ different processing mechanisms with familiar faces recognised via an invariant structural code and unfamiliar faces from the pictorial codes contained within an image of a face (Bruce and Young, 1986 British Journal of Psychology77305-327). Recent research has suggested however that p...
