The dispositional shift in attribution over time

Two experiments examined the effect of time on causal attributions. In Experiment I, subjects who described themselves into a tape recorder assumed more personal responsibility for their behavior after 3 weeks' time than others who explained their behavior immediately after its occurrence. In Experiment II, actor-subjects took part in a getting acquainted conversation and explained their behavior more dispositionally and less situationally after 3 weeks' time than they had initially, while observer-subjects experienced no change over time. Results were interpreted in terms of an altered self-perspective in memory and the diminished salience of situational details over time.     

Short-term memory in deaf and hearing children in relation to stimulus characteristics

Experiment 1 examined short-term memory with a serial probe task in 20 younger (mean age: 6 years, 3 months) and 20 older (mean age: 8 years, 8 months) deaf children. Four sets of stimuli were used: familiar animals, unfamiliar nonsense forms, fingerspelled letters, and lower-case print. In contrast to earlier research with hearing children, strong primacy effects were found with all stimuli at both ages, with frequent gestural and/or oral labeling but little cumulative rehearsal evident. To determine whether results were uniquely tied to deafness, identical procedures were used in Experiment 2 with 20 younger (4 years, 9 months) and 20 older (5 years, 10 months) hearing children. Again, overt activity was common, with strong primacy effects on animals and nonsense forms in the older group and on animals in the younger group. Contrasts between present and earlier findings suggest the need to consider the degree to which stimulus labels are overlearned, the role of nonverbal mediators in rehearsal, and the effects of changing educational experiences.     

Comment on “Visual layout modulates Fitts’s law: The importance of first and last positions”

Pratt, Adam, and Fischer (2007) investigated the effect of surrounding targets on the time it took to move to an individual target and found that the movement time to a central target was above the Fitts’s law line related to the first and last targets. They explained their results in terms of a “visuomotor hypothesis.” Here, an alternative explanation is given in terms of a previously validated model of the “available target width” that is determined by the size of the target and the width of the finger pad that is being used to hit the target.     

Decomposing animacy reversals between agents and experiencers: An ERP study

The present study aimed to refine current hypotheses regarding thematic reversal anomalies, which have been found to elicit either N400 or - more frequently - “semantic-P600” (sP600) effects. Our goal was to investigate whether distinct ERP profiles reflect aspectual-thematic differences between Agent-Subject Verbs (ASVs; e.g., ‘to eat’) and Experiencer-Subject Verbs (ESVs; e.g., ‘to love’) in English. Inanimate subject noun phrases created reversal anomalies on both ASV and ESV. Animacy-based prominence effects and semantic association were controlled to minimize their contribution to any ERP effects. An N400 was elicited by the target verb in the ESV but not the ASV anomalies, supporting the hypothesis of a distinctive aspectual-thematic structure between ESV and ASV. Moreover, the N400 finding for English ESV shows that, in contrast to previous claims, the presence versus absence of N400s for this kind of anomaly cannot be exclusively explained in terms of typological differences across languages.     

Crowding,Perceived Control,and Behavioral Aftereffects1

A laboratory experiment was conducted in which groups of Ss performed simple and complex tasks for one hour in three conditions of crowding: (1) noncrowded, (2) crowded, (3) crowded-with-perceived-control. Immediately afterward, all groups worked in a noncrowded situation on two additional tasks, one involving frustration tolerance and the other involving quality of proofreading performance. Conditions of crowding had no effect on simple or complex task performance. In the postcrowding situation, however, significant negative behavioral aftereffects were observed for the crowded groups on the frustration tolerance measure, though perceived control ameliorated these aftereffects. There were no significant aftereffects on the prooofreading measure.     

Generalization of Efficacy as a Function of Collective Action and Intergroup Relations: Involvement in an Anti‐Roads Struggle1

A questionnaire survey (n= 90) and an interview study (n= 63) of anti‐roads activities suggest links between participation and generalization. First, level of activism predicted whether others were perceived as encouraged to act environmentally. Second, participants' failure to stop construction of the road did not prevent them from developing related feelings of efficacy. Participants' perceptions of out‐groups were also examined. Participants were least hostile to those they defined as sharing their interests and capable of subjective change; they were most hostile to those seen as betraying the environmental cause. Practically, these findings suggest the importance of collective participation. Theoretically, the paper argues that efficacy theory be developed to acknowledge that identity can be collective as well as individual.
