Susceptibility to prosocial and antisocial influence in adolescence following mindfulness training

Mindfulness training programmes have shown to encourage prosocial behaviours and reduce antisocial tendencies in adolescents. However, less is known about whether training affects susceptibility to prosocial and antisocial influence. The current study investigated the effect of mindfulness training (compared with an active control) on self-reported prosocial and antisocial tendencies and susceptibility to prosocial and antisocial influence. 465 adolescents aged 11–16 years were randomly allocated to one of two training programmes. Pre- and post-training, participants completed a social influence task. Self-reported likelihood of engaging in prosocial and antisocial behaviours did not change post-training, and regardless of training group, participants showed a higher propensity for prosocial influence than for antisocial influence. Finally, participants were less influenced by antisocial ratings following both training programmes.     

A valence-specific lateral bias for discriminating emotional facial expressions in free field

Findings from subjects with unilateral brain damage, as well as from normal subjects studied with tachistoscopic paradigms, argue that emotion is processed differently by each brain hemisphere. An open question concerns the extent to which such lateralised processing might occur under natural, freeviewing conditions. To explore this issue, we asked 28 normal subjects to discriminate emotions expressed by pairs of faces shown side-by-side, with no time or viewing constraints. Images of neutral expressions were shown paired with morphed images of very faint emotional expressions (happiness, surprise, disgust, fear, anger, or sadness). We found a surprising and robust laterality effect: When discriminating negative emotional expressions, subjects performed significantly better when the emotional face was to the left of the neutral face; conversely, when discriminating positive expressions, subjects performed better when the emotional face was to the right. We interpret this valence-specific laterality effect as consistent with the idea that the right hemisphere is specialised to process negative emotions, whereas the left is specialised to process positive emotions. The findings have important implications for how humans perceive facial emotion under natural conditions.     

Reflections on the Meaning and Structure of the Horizontal/Vertical Distinction

The commentaries by Aaker (2006), Meyers‐Levy (2006), and Oyserman (2006) extend the implications of the horizontal/vertical distinction described in our article (Shavitt, Lalwani, Zhang, & Torelli, 2006) in a number of interesting directions. We join these authors in calling for further research on horizontal and vertical individualism and collectivism constructs. We also highlight conceptual and structural issues that remain to be resolved and evaluate priming and other operational approaches to the study of horizontal and vertical individualism and collectivism.     

Susceptibility to induction of long-term depression is associated with impaired memory in aged Fischer 344 rats

The current study employed aged and young male Fischer 344 rats to examine the relationship between long-term depression (LTD), age, and memory. Memory performance was measured on two tasks that are sensitive to hippocampal function; inhibitory avoidance and spatial discrimination on the Morris water maze. The slope of the extracellular excitatory postsynaptic field potential was recorded from CA3-CA1 synapses in hippocampal slices. Low frequency stimulation (LFS) induced a modest LTD only in aged animals under standard recording conditions. The decrease in synaptic transmission examined only in aged animals correlated with memory scores on the spatial task and LTD was not observed in aged animals with the highest memory scores. LTD induction was facilitated by increasing the Ca(2+)/Mg(2+) ratio of the recording medium or employing a paired-pulse stimulation paradigm. Age differences disappeared when LFS was delivered under conditions of elevated Ca(2+)/Mg(2+) in the recording medium. Using multiple induction episodes under conditions which facilitate LTD-induction, no age-related difference was observed in the maximum level of LTD. The results indicate that the increased susceptibility to LTD induction is associated with impaired memory and results from a shift in the induction process. The possible relationship between LTD and memory function is discussed.     

The ego dilemma and the Buddhist experience of enlightenment

The author examines the core problem of existence, the dread of nonbeing, from the standpoint of object-relations theory and subsequently demonstrates that the experience of enlightenment, emerging from religious mysticism, may be seen as the resolution of this basic human problem. The investigation of the experience of enlightenment is pursued from the perspective of Buddhism, a subject with which the author is most familiar.Ashok Kara, Ph.D., is a psychologist at the Southeast Memphis Mental Health Center and is also in part-time private practice.     

Organizational features of a young child's behaviors

The study was designed to investigate the nature of response-class phenomena and the possibility of indirect contingency control. A single subject was employed. Prior to the start of the study, the experimenter established the process of maintaining stimulus constancy during a preexperimental phase. Subsequent to the first baseline phase, a factor analysis was done to define the response class and the behavior categories constituting the class. Manipulating a single adult consequence to a response-class category over subsequent baseline and manipulation phases revealed frequency changes in all behavior categories in the response class. The data gave support to indirect behavior control. Search for possible explanations of frequency changes showed that the direction of the frequency changes were predictable from the results of the factor analysis.     

Perceptions of Parenting Style Among College Students in India and the United States

Although a growing body of psychological literature has examined the influence of culture on parenting style, relatively less attention has been paid to gender differences in parenting style across cultures. The present study examined perceptions of parenting style as a function of participant’s culture, participant’s gender, and parent gender in college students in India and the United States. Using a new vignette-based self-report measure that characterizes each of Baumrind’s three parenting styles, participants rated perceptions of effectiveness, helpfulness, caring, and normativeness of each style. Contrary to expectation, results showed that Indian college students considered the parent demonstrating permissive parenting to be more effective and helpful than US college students. In contrast, US college students considered the parents demonstrating authoritative and authoritarian parenting to be more effective, helpful, and caring than Indian college students. A majority of Indian and US college students selected the parent demonstrating authoritative parenting as most similar to their own parents, and the type of parent they wish to be in the future. Females considered the parent demonstrating authoritative parenting to be more effective and helpful than males. Relatively few effects of parent gender were found.     

Identifying facial emotions: valence specific effects and an exploration of the effects of viewer gender

The valence hypothesis suggests that the right hemisphere is specialised for negative emotions and the left hemisphere is specialised for positive emotions (Silberman & Weingartner, 1986). It is unclear to what extent valence-specific effects in facial emotion perception depend upon the gender of the perceiver. To explore this question 46 participants completed a free view lateralised emotion perception task which involved judging which of two faces expressed a particular emotion. Eye fixations of 24 of the participants were recorded using an eye tracker. A significant valence-specific laterality effect was obtained, with positive emotions more accurately identified when presented to the right of centre, and negative emotions more accurately identified when presented to the left of centre. The valence-specific laterality effect did not depend on the gender of the perceiver. Analysis of the eye tracking data showed that males made more fixations while recognising the emotions and that the left-eye was fixated substantially more than the right-eye during emotion perception. Finally, in a control condition where both faces were identical, but expressed a faint emotion, the participants were significantly more likely to select the right side when the emotion label was positive. This finding adds to evidence suggesting that valence effects in facial emotion perception are not only caused by the perception of the emotion but by other processes.     

The Horizontal/Vertical Distinction in Cross‐Cultural Consumer Research

We argue for the importance of a relatively new cultural distinction in the horizontal (valuing equality) or vertical (emphasizing hierarchy) nature of cultures and cultural orientations. A review of the existing cross‐cultural literature is presented suggesting that, although the contribution of the horizontal/vertical distinction is sometimes obscured by methods that conflate it with other dimensions, its impact is distinct from that associated with individualism–collectivism. We present studies that highlight several sources of value for the horizontal/vertical distinction—as a predictor of new consumer psychology phenomena and as a basis for refining the understanding of known phenomena. Results support the utility of examining this distinction for the understanding of personal values, advertising and consumer persuasion, self‐presentational patterns, and gender differences. Methodological issues in studying the horizontal/vertical distinction are also discussed.
