Ear differences in simple reaction time: The influence of attentional factors

Simple motor reaction times (right-handed) to tape-recorded consonant-vowel syllables were obtained from 12 subjects under two conditions of monotic stimulation: “expected” presentation (subject informed as to ear of presentation) and “random” presentation (ear of presentation varied randomly). Significantly faster left ear reaction times were obtained in the “expected” condition. The rank order of subjects' standard dichotic listening task scores correlated negatively with reaction time ear differences in the “expected” presentation condition. Results are discussed in terms of existing theories of response lateralization in simple reaction time tasks, and an expanded hypothesis is offered. Specifically, it is suggested that two or more distinct but potentially overlapping mechanisms may be responsible for observed asymmetries in monotic auditory perception. Both an attentional or lateralized motor response bias and an inherent lateralization of function may operate side by side, differentially activated by task demands, mode of stimulus presentation, and nature of stimuli.     

Sex differences in self-disclosure: Effects of topic content,friendship, and partner's sex

Male-female differences in self-disclosure were found as a function of sex stereotyping of topic content. Men disclosed less than women on “feminine” topics, which emphasized personal concerns and sensitivities. Men and women did not differ in disclosure on “neutral” topics, considered appropriate for both sexes to discuss. Men and women did not differ in disclosure on “masculine” topics (emphasizing assertiveness) in two of three experiments. Theoretical mechanisms that might mediate sex differences in self-disclosure were considered.     

The role of Canadian school psychologists: Perceptions of a sample from the general public

A sample of 77 subjects responded to a questionnaire designed to collect information about their perceptions of the role of school psychologists. The results indicate that overall the respondents had a fairly accurate sense of what a school psychologist does, although they overestimated the importance of psychotherapy as one of the school psychologist's functions. It is recommended that school psychologists more clearly specify their function when dealing with members of the general public.     

The effect of phonemic processing on the retention of graphemic representations for words and nonwords

The three experiments reported in this study were each conducted in two phases. The first phase of Experiment 1 involved a same-different comparison task requiring “same” responses for both mixed-case (e.g., MAIN main) and pure-case (e.g., near near) pairs. This was followed by Phase 2, a surprise recognition test in which a graphemic effect on word retention was indicated by the superior recognition accuracy obtained for pure-case compared with mixed-case pairs. The first phases of Experiments 2 and 3 involved pronounceability and imageability judgment tasks, respectively. Graphemic retention was assessed by contrasting recognition accuracy for letter strings presented, during Phase 2, in their original Phase 1 case, with letter strings presented, during Phase 2, in. a graphemically dissimilar new case. The experiments provided evidence that there was minimal retention of the graphemic representations from which the phonemic representations of words are generated and, further, that the locus of this effect is probably postlexical. Nonwords were recognized more accurately than words in all three experiments. The latter result was attributed to differences between nonwords and words in both graphemic retention and semantic distinctiveness.     

Meeting a deviant person: Subjective norms and affective reactions

Studied differences in verbal, nonverbal, and physiological responses during a confrontation with a male confederate role-playing either a physically handicapped (PH), homosexual (HS), or normal (NOR) person. One hundred and eight males from colleges of economics and engineering listened in a laboratory experiment to personal introductions by two confederates in succession. Whereas the first confederate always appeared normal, the second took one of the three roles mentioned. A further informal meeting with this confederate was arranged outside the laboratory; all subjects had taken a stereotype test before. Normative differences between PH and HS (p ≤ 0.05) are found on verbal measures including the stereotype test, self-rated emotion and consent to a further contact. General effects of deviance separating PH and HS from NOR (p ≤ 0.05) emerge on observed emotion, interpersonal distance during the informal meeting, and skin-resistance responses. The results largely confirm the hypotheses. They are interpreted as supporting a distinction between intended (action-type) components of behaviour which are strongly influenced by subjective norms, and unintended (reaction-type) components reflecting undifferentiated reactions to deviance.     

Perception of emotions by accepted and rejected children

The purpose of this study was to assess the perceptions of emotions by accepted and rejected children. Peer ratings and peer sociometrics were used to identify accepted and rejected children. All children were administered a task specifically designed to measure their ability to perceive emotions. This task consisted of a series of videotaped interactions involving two individuals—either two adults or two children—portraying one of three affective states: happiness, sadness, and anger. After viewing each interaction, children were asked to identify what the person was feeling. In addition, teachers and peers rated the children on their ability to perceive emotions in others. The results indicated that accepted children obtained significantly higher scores than rejected children on the identification of emotions in the interactions. Teachers and peers also rated accepted children as better perceivers of emotions than rejected children. Implications of the results are discussed.     

Hemiplegic writing in severe aphasia

Three patients with severe aphasia and right hemiplegia are described who could write to dictation with the right arm using a limb prosthesis though agraphic with the "intact" left hand. The phenomenon of "hemiplegic writing" is explained as an access to submerged or preprocessing levels in language and action structure, through the use of older proximal motor systems. This interpretation has implications for our understanding of language and brain function, as well as for approaches to the treatment of patients with severe language disorders.     

Programmed stuttering therapy for children: Comparison of four establishment programs

Four different establishment programs (programmed traditional, delayed auditory feedback, pause, and gradual increase in length and complexity of utterance) for improving the fluency of school-age children who stutter were compared. The programs were carried out by eight public school clinicians with 16 children (eight elementary and eight junior-senior high school) in their respective schools. All four programs produced important improvement in the speech fluency of the 16 children. All the children demonstrated transfer of fluency to extratraining settings. The delayed auditory feedback program required the least therapy hours, but it was difficult for the clinicians to operate correctly. The gradual increase in length and complexity of utterance programs produced the best overall results. The transfer and maintenance programs provided for additional generalization and permanency of fluency. Follow-up revealed that the children continued their increased level of fluency.
