Peers,Social Control,or Guilt? Self-Conscious Emotions as Explanation for Antisocial Behavior

Criminologists rarely include self-conscious emotions like guilt or shame to explain delinquency. Instead, factors external to the individual are often used, such as social institutions, the family, or peers. This study uses a longitudinal sample of 526 youth from two waves of survey data to assess the effects of peer influences, social control, and the self-conscious emotion of guilt on youth problem behaviors. Problem behavior is measured using teacher assessments at Time2. All other variables are baseline youth self-report measures that were collected at Time1. The results show that guilt statistically predicted teacher-assessed problem behaviors. Further work is needed to develop this measure in criminology.     

Common features of fluency-evoking conditions studied in stuttering subjects and controls: an H2O PET study

We used H₂¹⁵O PET to characterize the common features of two successful but markedly different fluency-evoking conditions — paced speech and singing — in order to identify brain mechanisms that enable fluent speech in people who stutter. To do so, we compared responses under fluency-evoking conditions with responses elicited by tasks that typically elicit dysfluent speech (quantifying the degree of stuttering and using this measure as a confounding covariate in our analyses). We evaluated task-related activations in both stuttering subjects and age- and gender-matched controls.

Areas that were either uniquely activated during fluency-evoking conditions, or in which the magnitude of activation was significantly greater during fluency-evoking than dysfluency-evoking tasks included auditory association areas that process speech and voice and motor regions related to control of the larynx and oral articulators. This suggests that a common fluency-evoking mechanism might relate to more effective coupling of auditory and motor systems — that is, more efficient self-monitoring, allowing motor areas to more effectively modify speech.

These effects were seen in both PWS and controls, suggesting that they are due to the sensorimotor or cognitive demands of the fluency-evoking tasks themselves. While responses seen in both groups were bilateral, however, the fluency-evoking tasks elicited more robust activation of auditory and motor regions within the left hemisphere of stuttering subjects, suggesting a role for the left hemisphere in compensatory processes that enable fluency.

Educational objectives: The reader will learn about and be able to: (1) compare brain activation patterns under fluency- and dysfluency-evoking conditions in stuttering and control subjects; (2) appraise the common features, both central and peripheral, of fluency-evoking conditions; and (3) discuss ways in which neuroimaging methods can be used to understand the pathophysiology of stuttering.     

Syntax in pictures

It was hypothesised that pictures drawn to represent active and passive sentences would reflect this syntactic difference. Specifically, it was predicted that the reversal of the order in which the logical subject (LS) and the logical object (LO) occur in the change from active to passive form of sentence will affect the order in which they occur in their pictorial representations. A significant directional preference was found for placing the LO to the left of the LS in the pictorial representations of passive but not active sentences. This was discussed in terms of the marked status of the passive in relation to the active. In the case of sentences differing only in lexical marking there was no asymmetric directionality effect corresponding to that found for actives and passives. A significant tendency to match the surface order of the sentences in the pictures was found for both lexically marked and unmarked sentences. The possibility that other spatial or physical dimensions might be used to express syntactic and semantic factors in the pictorial representation of sentences is considered.     

Exploring early self‐referential memory effects through ownership

The self‐reference effect (SRE) is the reliable memory advantage for information encoded about self over material encoded about other people. The developmental pathway of the SRE has proved difficult to chart, because the standard SRE task is unsuitable for young children. The current inquiry was designed to address this issue using an ownership paradigm, as encoding objects in the context of self‐ownership have been shown to elicit self‐referential memory advantages in adults. Pairs of 4‐ to 6‐year‐old children (n = 64) sorted toy pictures into self‐ and other‐owned sets. A surprise recognition memory test revealed a significant advantage for toys owned by self, which decreased with age. Neither verbal ability nor theory of mind attainment predicted the size of the memory advantage for self‐owned items. This finding suggests that contrary to some previous reports, memory in early childhood can be shaped by the same self‐referential biases that pervade adult cognition.
