Maternal Modeling and the Acquisition of Fear and Avoidance in Toddlers: Influence of Stimulus Preparedness and Child Temperament

The aim of the present study was to investigate the influence of maternal modeling on the acquisition of fear and avoidance towards fear-relevant and fear-irrelevant, novel stimuli in a sample of 71 toddlers. Children were shown a rubber snake or spider (fear-relevant objects) and a rubber mushroom or flower (fear-irrelevant objects), which were alternately paired with either negative or positive expression by their mothers. Both stimuli were presented again after a 1- and a 10-min delay, while mothers maintained a neutral expression. The toddlers showed increased fear and avoidance of the objects following negative reaction from their mothers than following positive maternal expression. This was similarly true for both fear-relevant and fear-irrelevant stimuli. In addition, no association was found between child temperament and behavioral responses and a weak association emerged between child temperament and emotional responses. The results demonstrate that young children can rapidly form conditioned emotional and behavioral responses via maternal reactions regardless of stimulus preparedness or child temperament. It is suggested that early maternal modeling may be relevant to a broad spectrum of fearful reactions.     

Predicting individual change in support over time among chronically impaired older adults

Hierarchical linear modeling was used to examine the degree of individual change in friendship and family networks and support over time as a function of sociodemographic characteristics, rehabilitation use, and disability. Participants, 449 older adults, had age-related vision loss, a common, chronic impairment that tends to worsen over time. Three interviews were conducted (baseline and 6- and 18-month follow-ups). All network and support variables showed a decrease over time. Regarding factors predicting individual variation, age (younger) and education (lower) were associated with greater baseline friendship support, rehabilitation was related to maintaining a larger friend network, and disability was positively associated with family network and support. Results supported the importance of examining rates of individual change and factors associated with variability in multiple support components by relationship type.     

Challenging perceptual tasks require more attention: The influence of task difficulty on the N1 effect of temporal orienting

Both filter and resource models of attention suggest an influence of task difficulty on the size of early attention effects. As for temporal orienting, the idea that early effects are modulated by task difficulty has not been tested directly, so far. To fill this empirical gap, the present study used an auditory temporal-orienting task, in which two differently pitched pure tones served as targets. To manipulate perceptual difficulty, the pitch difference between the targets was either small or large. Temporal orienting enhanced the N1 component of the auditory event-related potential. This early, sensory effect tended to be larger in the more difficult condition, particularly over the frontal scalp. Notably, increasing task difficulty affected predominantly the processing of attended stimuli. Hence, temporal orienting may operate by increasing processing resources or gain settings for the attended time point – rather than by withdrawing resources from the unattended time point.     

The easily learned,easily remembered heuristic in children

A previous study with adults [Koriat, A. (2008a). Easy comes, easy goes? The link between learning and remembering and its exploitation in metacognition. Memory & Cognition, 36, 416–428] established a correlation between learning and remembering: items requiring more trials to acquisition (TTA) were less likely to be recalled than those requiring fewer trials. Furthermore, learners’ judgments of learning (JOLs) seemed to rely on the easily learned, easily remembered (ELER) heuristic, that items requiring fewer TTAs are more likely to be recalled. This study extended investigation of these effects to 2nd- and 4th-grade children. When the list included hard and easy paired-associates (Experiment 1, N = 40, 7–10 years), recall and JOL decreased with increasing TTAs for both grades, supporting the validity of the ELER heuristic and its utilization in monitoring one's own learning. When presented only with hard pairs (Experiment 2, N = 60, 7–10 years), however, 4th graders’ but not 2nd graders’ JOLs evidenced reliance on this heuristic. The results suggest an early development of metacognitive heuristics that incorporate information about the links between characteristics of the encoding process and subsequent remembering.     

Themes of Self‐Regulation and Self‐Exploration in the Life Stories of Religious American Conservatives and Liberals

A sample of 128 highly religious (Christian) midlife American adults completed a series of attitudinal and personality trait measures and narrated 12 important autobiographical scenes in their life stories. Individuals high on self‐reported political conservatism tended to accentuate the theme of self‐regulation in their life stories, repeatedly describing important autobiographical scenes wherein they struggled to control, discipline, manage, restrain, protect, or preserve the self. By contrast, individuals high on political liberalism tended to emphasize the theme of self‐exploration, telling stories about expanding, discovering, articulating, or fulfilling the self. Demographics and dispositional traits (especially openness to experience) showed significant associations with conservatism‐liberalism, as well, but these variables did not mitigate the robust relationship between life‐narrative themes and political orientation. The results are discussed in terms of a broadened understanding of personality that conceives of dispositional traits and narrative identity as comprising distinct layers and complementary features of psychological individuality, both implicated in political lives.
