Healthy or wealthy? Attractive individuals induce sex-specific food preferences

Healthy or wealthy? Attractive individuals induce sex-specific food preferences. Tobias Otterbring. Food Quality and Preference, https://doi.org/10.1016/j.foodqual.2017.02.014

Highlights
•    Attractive men decrease women’s preferences for unhealthy foods.
•    Attractive men increase women’s preferences for healthy foods.
•    Women’s level of restrained eating moderates this effect.
•    Attractive women increase men’s preferences for expensive foods and beverages.
•    Men’s desire to display status mediates this effect.

Abstract: Research shows that the mere presence of others and their physical appearance can influence people’s meal choices and food intake. Studies also suggest that such effects are sex-specific and depend on whether the eating occasion includes same-sex or opposite-sex individuals. In five experiments (N = 530; 49% female), the author investigates whether mate attraction, induced by exposure to attractive opposite-sex individuals, has a differential effect on the foods and beverages that men and women prefer to consume. The results revealed that prior exposure to attractive (versus less attractive) men decreased women’s willingness to spend money on unhealthy foods, and increased their inclination to spend money on healthy foods. Restrained eating moderated this effect, which means that women who scored high (versus low) on restrained eating were particularly motivated to spend money on healthy foods after exposure to an attractive male individual. On the contrary, exposure to attractive (versus less attractive) women did not influence men’s consumption preferences for healthy or unhealthy foods. However, men were more motivated to spend money on expensive drinking and dining options after exposure to an attractive female individual, and their desire to display status mediated this effect. Importantly, none of these effects occurred after exposure to attractive same-sex individuals, which provides converging evidence that mate attraction is the fundamental motive underlying these findings. Taken together, this research reveals how, why, and when appearance-induced mate attraction leads to sex-specific consumption preferences for various foods and beverages.

The idea that speaking in a certain way can make people do things –persuasion on steroids, so to say– is understandably fascinating; its use by pick-up artists is examined

In other words: ‘The language of attraction’ used by pick-up artists. Daria Dayter and Sofia Rüdiger. English Today, https://doi.org/10.1017/S026607841800007X

Extract: The idea that speaking in a certain way can make people do things – persuasion on steroids, so to say – is understandably fascinating. This holy grail of communication studies is sought after by ‘professional persuaders’, politicians and copywriters, but also in non-professional situations. One example of wishful thinking of what is possible when it comes to the power of language is the Pick-up Artist (PUA) paradigm. PUAs are a community of self-designated or aspiring seduction experts; and it should come as no surprise that most members are men. While it is possible for PUAs to meet face-to-face, for example, at workshops organized by the so-called gurus (at no little cost to the students of pick-up), much of the interaction between the members takes place in PUA Internet forums and similar online venues.

Cognitive and affective mental states penetrate visual processing, and can affect the system’s behaviour, structure and perceptual content

Cognitive penetration of early vision in face perception. Ariel S. Cecchi. Consciousness and Cognition, https://doi.org/10.1016/j.concog.2018.06.005

Highlights
•    Cognitive and affective mental states penetrate visual processing.
•    This influence can affect the system’s behaviour, structure and perceptual content.
•    Psychological evidence is not sufficient to argue for the penetration of perception.
•    Psychological evidence is not necessary to argue for the penetration of perception.
•    The penetration of visual perception needs to be assessed by neuroscientific evidence.
•    A neurocientific study appears to show higher influences in early visual content.
•    It is concluded that this study shows a case of cognitive penetration of early vision.
•    Alternative explanations to this conclusion are considered and rejected.

Abstract: Cognitive and affective penetration of perception refers to the influence that higher mental states such as beliefs and emotions have on perceptual systems. Psychological and neuroscientific studies appear to show that these states modulate the visual system at the visuomotor, attentional, and late levels of processing. However, empirical evidence showing that similar consequences occur in early stages of visual processing seems to be scarce. In this paper, I argue that psychological evidence does not seem to be either sufficient or necessary to argue in favour of or against the cognitive penetration of perception in either late or early vision. In order to do that we need to have recourse to brain imaging techniques. Thus, I introduce a neuroscientific study and argue that it seems to provide well-grounded evidence for the cognitive penetration of early vision in face perception. I also examine and reject alternative explanations to my conclusion.

False intentions are more abstractly depicted than true intentions

Drawing what lies ahead: False intentions are more abstractly depicted than true intentions. Sofia Calderon, Erik Mac Giolla, Karl Ask, Pär Anders Granhag. Applied Cognitive Psychology, https://doi.org/10.1002/acp.3422

Abstract: The aim of this study was to examine how people mentally represent and depict true and false statements about claimed future actions—so‐called true and false intentions. On the basis of construal level theory, which proposes that subjectively unlikely events are more abstractly represented than likely ones, we hypothesized that false intentions should be represented at a more abstract level than true intentions. Fifty‐six hand drawings, produced by participants to describe mental images accompanying either true or false intentions, were rated on level of abstractness by a second set of participants (N = 117) blind to the veracity of the intentions. As predicted, drawings of false intentions were rated as more abstract than drawings of true intentions. This result advances the use of drawing‐based deception detection techniques to the field of true and false intentions and highlights the potential for abstractness as a novel cue to deceit.

Why Does the Cortex Reorganize after Sensory Loss? Don't know, but possibilities besides compensation include unmasking of dormant inputs, and mitigation of potentially harmful physiological changes in deafferented cortical tissue

Why Does the Cortex Reorganize after Sensory Loss? Amy Kalia Singh et al. Trends in Cognitive Sciences, https://doi.org/10.1016/j.tics.2018.04.004

Highlights

Neuroimaging studies have revealed that after loss of their primary sensory inputs, cortical areas often come to exhibit responses to inputs from other sensory modalities.

These cortical changes are sometimes, but not always, accompanied by enhancements in behavioral abilities in the encroaching modalities, seemingly to compensate for the missing modality.

We lack a comprehensive account of why cortical reorganization happens after sensory loss. Possibilities besides compensation include unmasking of dormant inputs, and mitigation of potentially harmful physiological changes in deafferented cortical tissue.

Abstract: A growing body of evidence demonstrates that the brain can reorganize dramatically following sensory loss. Although the existence of such neuroplastic crossmodal changes is not in doubt, the functional significance of these changes remains unclear. The dominant belief is that reorganization is compensatory. However, results thus far do not unequivocally indicate that sensory deprivation results in markedly enhanced abilities in other senses. Here, we consider alternative reasons besides sensory compensation that might drive the brain to reorganize after sensory loss. One such possibility is that the cortex reorganizes not to confer functional benefits, but to avoid undesirable physiological consequences of sensory deafferentation. Empirical assessment of the validity of this and other possibilities defines a rich program for future research.
