Stability in young infants' discrimination of optic flow

Although considerable progress has been made in understanding how adults perceive their direction of self-motion, or heading, from optic flow, little is known about how these perceptual processes develop in infants. In 3 experiments, the authors explored how well 3- to 6-month-old infants could discriminate between optic flow patterns that simulated changes in heading direction. The results suggest that (a) prior to the onset of locomotion, the majority of infants discriminate between optic flow displays that simulate only large (> 22 deg.) changes in heading, (b) there is minimal development in sensitivity between 3 and 6 months, and (c) optic flow alone is sufficient for infants to discriminate heading. These data suggest that spatial abilities associated with the dorsal visual stream undergo prolonged postnatal development and may depend on locomotor experience.     

Correlations between attitude toward Christianity, prayer, and church attendance among 9- to 11-yr.-olds

Data provided by 150 9- to 11-yr.-old primary school pupils in England showed scores on the Francis Scale of Attitude toward Christianity more highly correlated with (personal) prayer (r = .57) than with (public) church attendance (r = .23), providing support for the view that attitude scales access a deeper level of religiosity less contaminated by those contextual and social factors which may influence public church attendance more than personal prayer.     

The forest, the trees, and the chameleon: context dependence and mimicry

Three studies examined the relation between context dependence in information processing and behavioral mimicry. In Experiment 1, a field-dependent cognitive style was related to a greater tendency to mimic a target's behavior. In Experiment 2 context dependence was experimentally manipulated, and results showed more mimicry in the session where a context-dependent processing style was induced compared with the session where a context-independent processing style was induced. Experiment 3 provided evidence for bidirectionality in the relation between context dependence and mimicry. Specifically, participants whose posture and behavior had been unobtrusively mimicked by an experimenter subsequently processed information in a more context-dependent manner than did nonmimicked participants. Taken together, these results illustrate the interplay between basic cognitive and behavioral processes.     

It's the thought that counts: on perceiving how helpers decide to lend a hand

How do people react to those who have helped them? The authors propose that a recipient's evaluation of a helper's intentions and the recipient's own attitudes about future interactions with the helper depend partly on the recipient's perceptions of how the helper decided to assist: on the basis of affect, of role, or of cost-benefit calculation. When a recipient perceives that the decision was based on affect (i.e., positive feelings about him or her), he or she will be more inclined toward future interaction and reciprocation than if he or she perceives the decision as based on role or cost-benefit calculation. It is proposed that these "decision modes" signal the helper's underlying attitudes about the recipient, which in turn, clarify their relationship. A boundary is also identified: The negative impact of apparent cost-benefit thinking is greatest when the amount of help provided is small. Predictions are confirmed in four studies of actual and experimentally manipulated helping episodes.     

Habituation assessment in infancy

Infant-control habituation methodology, although serving the research community well, has never been carefully analyzed. A main use is to equate infants in their level of habituation prior to experimental manipulations in a posthabituation phase. When studied analytically and with simulation, it is found to have serious difficulties. It inadvertently recruits infants with large variations in performance while discriminating against those with less variable performance. For nonhabituating infants, its Type I error rates can approach 1. A model-based nonlinear regression framework is proposed, which, because of large individual differences in infants, takes as the unit of analysis the individual infant. It is shown to be more powerful and efficient than existing procedures and can offer practical and theoretical benefits.     

Attachment style and individual differences in leadership perceptions and emergence

The authors examined whether individuals' approaches to relationships, expressed in terms of attachment styles, was related to how they viewed ideal leadership and to their degree of tendency to emerge as team leaders. Specifically, the authors hypothesized that attachment styles, or cognitive representations of orientation to others, would explain individual differences in leadership perceptions and emergence. Participants were 127 American students in college teams. The authors found that securely attached individuals (n = 81) perceived themselves as more effective team members than did insecurely attached individuals (n = 46) and that fellow team members saw securely attached team members as emerging team leaders significantly more often than they did insecurely attached team members.     

Personality and attitude toward Christianity among churchgoers: a replication

A sample of 158 churchgoers attending eight Anglican churches in the United Kingdom completed the abbreviated Revised Eysenck Personality Questionnaire together with the Francis Scale of Attitude toward Christianity to replicate a 1996 study by Carter, Kay, and Francis. Data confirm that scores on Attitude toward Christianity were significantly negatively related to Psychoticism, but to neither Extraversion nor Neuroticism scores.     

Attitude toward Christianity and premarital sex

A Pearson correlation of .55 was found for a sample of 243 female undergraduates in Wales (M age=20.9 yr., SD=4.6) between high scores on the Francis Scale of Attitude toward Christianity and rejection of premarital sex.     

Attention Deficit-Hyperactivity Disorder, Depression, and Self- and Other-Assessments of Social Competence: A Developmental Study

This study examined whether others (i.e., teachers and parents) and self-appraisals of social competence mediated the relationship between Attention-Deficit/Hyperactivity Disorder (ADHD) and depression. To determine whether age moderated the effects of the mediation, the total sample was divided into younger (under 9) and older (at or above 9 years) age levels. The total sample (age range 6.6 to 11.7 years) was primarily male (194 boys and 52 females) and consisted of 148 children diagnosed with ADHD and 98 community controls. Three central findings were derived from this study. First, there was a strong relationship between ADHD (with and without comorbid ODD/CD) and depression in both younger and older aged children. Among younger children with ADHD, there was no differential influence on the level of depression depending on whether or not ADHD was comorbid with ODD/CD; in contrast, with older children, comorbid ODD/CD had higher levels of depression than was the case for children with ADHD that did not display such comorbidity. Second, with younger children approximately half of the relationship between ADHD (with and without comorbid ODD/CD) and depression was exclusively mediated by others appraisal of social competence. Third, a more complex relationship between ADHD and depression emerged during the later part of the childhood years. As such, the relationship between ADHD, others appraisals of social competence, and depression was further mediated by self-appraisals of social competence. Findings are discussed in terms of developmental theory and theoretical models of childhood depression.Rick Ostrander and David S.

Linking automatic evaluation to mood and information processing style: consequences for experienced affect, impression formation, and stereotyping

According to the feelings-as-information account, a person's mood state signals to him or her the valence of the current environment (N. Schwarz & G. Clore, 1983). However, the ways in which the environment automatically influences mood in the first place remain to be explored. The authors propose that one mechanism by which the environment influences affect is automatic evaluation, the nonconscious evaluation of environmental stimuli as good or bad. A first experiment demonstrated that repeated brief exposure to positive or negative stimuli (which leads to automatic evaluation) induces a corresponding mood in participants. In 3 additional studies, the authors showed that automatic evaluation affects information processing style. Experiment 4 showed that participants' mood mediates the effect of valenced brief primes on information processing.
