A new method of monitoring motor activity in baboons

Movement activity of a normal baboon and of a baboon with induced Parkinsonism by unilateral administration of 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP) was recorded by the Walter Reed Activity Monitor (or actigraph). Mean activity in the lesioned baboon was 41% less than that of the nonlesioned baboon measured over a 14-day period. In addition, the daily maximum activity value was significantly less in the MPTP-treated baboon. Moreover, resting and sleeping periods were 30% greater in the lesioned animal. The akinesia and resting and sleeping periods were displayed by the lesioned baboon throughout the day, whereas the control baboon showed them only at night. The data representing summarized movement activity are in accordance with observations of bradykinesia, hypokinesia, and akinesia of the MPTP-treated baboon. The actigraph was well tolerated by the animal because its small size and weight made it largely unobtrusive. We suggest that the actigraph is an appropriate device for measuring motor activity in nonhuman primates.     

Social-Emotional Adjustment and Patterns of Alcohol Use among Young Adults

ABSTRACT Individual differences in social-emotional adjustment, jointly defined by levels of distress and self-restraint, were used to evaluate (a) patterns of alcohol use, (b) reasons for use, and (c) associated problems in two college samples of young adults (N= 287 and N= 215). As hypothesized, low self-restraint was associated with high levels of alcohol use, drinking to increase positive affect, and high levels of alcohol-related problems. Subjective distress was not related to levels of use; however, it was associated with drinking to escape negative moods and social discomfort and with excessive alcohol-related problems. Both high distress and low self-restraint predicted problem drinking beyond what could be accounted for by quantity or frequency of alcohol use or by peers' use. Within Weinberger and Schwartz's (1990) six-group typology, reactive individuals (high distress–low restraint) were especially likely to be problem drinkers, even when compared to groups with equivalent alcohol use. In a separate study, knowledgeable peers' reports validated the differences between reactive and repressive individuals, the two groups most likely to have inaccurate self-reports.     

The family origins of empathic concern: a 26-year longitudinal study

This study examined whether adult empathic concern was associated with parent behavior in early childhood. Subjects were drawn from a longitudinal sample first investigated by Sears, Maccoby, and Levin (1957). At age 31, 75 subjects completed the Adjective Checklist (Gough & Heilbrun, 1965, 1983), from which an index of empathic concern was derived. Scores on this index were regressed on 11 parenting dimensions derived from maternal interviews when the subjects were 5 years old. The results revealed a significant multiple R indicating that, taken together, the parenting dimensions predicted the level of empathic concern at age 31. Adult levels of empathic concern were most strongly related to the following parenting dimensions: paternal involvement in child care, maternal tolerance of dependent behavior, maternal inhibition of child's aggression, and maternal satisfaction with the role of mother.     

Extraversion and rapid tapping: reactive inhibition or general cortical activation as determinants of performance differences

Two samples of subjects (n_tot = 22) scoring high or low on EPI-E tapped a morse-key as fast as possible over a 2-min period. As predicted, extraverts showed a lower tapping performance than introverts with differences between groups increasing significantly over time due to greater delays among the extraverts. Within the E dimension tapping differences could be shown to depend significantly only on the subfactor impulsiveness but not on sociability. There were no differences between groups, however, in frequency of involuntary rest pauses. Therefore the effects of extraversion on tapping performance should be explained more in terms of underlying differences in cortical arousal level than in terms of intermittent blocks as part of inhibitory potentials.     

Effects of "favorability" and type of assessment device upon acceptance of general personality interpretations

College students' acceptance of general personality interpretations was evaluated as a function of type of test and assessment device employed and interpretation favorability. Unlike previous studies, only interpretation favorability influenced acceptance. The effect of interpretation favorability upon acceptance, however, was shown to be due to the higher base-rate accuracy of favorable, relative to unfavorable, interpretations. It was concluded that the universal validity of general interpretations may supersede the effects of situational factors upon acceptance.     

Patterns of emotional responses to affective situations: Relations among happiness,sadness, anger,fear, depression,and anxiety

Although emotion research and clinical practice often implicitly entail judgments about the patterns and situational appropriateness of a person's emotional reactions, we have little empirical knowledge of how emotions typically interrelate during various affective situations. To assess patterns of response to normative situations, a questionnaire was constructed and validated to include items primarily eliciting one of six emotions (happiness, sadness, anger, fear, depression, and anxiety) and one of three intensities (low, moderate, and high). A total of 216 persons rated one of four forms of the questionnaire on each of the six emotional categories. Each of the six types of situations generated significantly different patterns of emotion. As Izard (1972) predicted, depression situations elicited more complex patterns of emotion than sadness situations, including significantly more anger, fear, and anxiety. In contrast, anxiety situations did not elicit more complex patterns than fear situations. Rather, the evidence was more consistent with the conclusion that fear is a particular type of anxiety. Various other relations among specific emotions are discussed, as well as some subtle sex differences and intensity effects. The data highlight the sensitivity with which the assessment of patterns of emotions associated with specific situations can produce new information about the nature of affective experience.     

Experience,Effectiveness, and Perceptions Toward Sport Psychology Consultants: A Critical Review of Peer-Reviewed Articles

The first scientific papers on sport psychology consultants (SPCs) focused primarily on the professional practice of experienced SPCs. Since then, the scientific literature on SPCs has greatly diversified. The purpose of this review is to summarize and critically examine the findings of three scientifically studied topics on SPCs: SPCs' experiences, perceptions toward SPCs, and SPCs' effectiveness. Peer-reviewed scientific articles published in English were found in the main sport and psychology databases. The primary results in relation to each topic and the limitations of these papers are presented. The discussion examines future avenues from which to develop research on SPCs.     

Neuroethical and Social Implications of Using Transcranial Electrical Stimulation to Augment Creative Cognition

Recent research indicates that transcranial electrical stimulation (tES) of specific brain regions can successfully improve various forms of creative cognition. Although the endeavor to increase human creative capacity is intriguing from a neuroscientific perspective, and of interest to the general public, it raises numerous neuroethico-legal and social issues (NELSI). This review explores these issues by considering (a) whether using brain stimulation to improve creative cognition qualifies as a ‘treatment’ or an ‘enhancement,’ (b) how direct-to-consumer (DTC) and do-it-yourself (DIY) use of tES should be regarded and regulated, and (c) what the developing landscape of creativity-related neurostimulation could (and should) become.     

When preschoolers follow their eyes and older children follow their noses: visuo‐olfactory social affective matching in childhood

Recognition of emotional facial expressions is a crucial skill for adaptive behavior that most often occurs in a multi‐sensory context. Affective matching tasks have been used across development to investigate how people integrate facial information with other senses. Given the relative affective strength of olfaction and its relevance in mediating social information since birth, we assessed olfactory–visual matching abilities in a group of 140 children between the ages of 3 and 11 years old. We presented one of three odor primes (rose, fish and no‐odor, rated as pleasant or unpleasant by individual children) before a facial choice task (happy vs. disgusted face). Children were instructed to select one of two faces. As expected, children of all ages tended to choose happy faces. Children younger than 5 years of age were biased towards choosing the happy face, irrespective of the odor smelled. After age 5, an affective matching strategy guided children's choices. Smelling a pleasant odor predicted the choice of happy faces, whereas smelling the unpleasant or fish odor predicted the choice of disgusted faces. The present study fills a gap in the developmental literature on olfactory‐visual affective strategies that affect decision‐making, and represents an important step towards understanding the underlying developmental processes that shape the typical social mind.
