A technique for controlling speech disfluencies induced by delayed auditory feedback

On the basis of cybernetic models of speech it was hypothesized that “stuttering” induced by delayed auditory feedback could be significantly reduced if the Ss were provided with an alternate input to which they could attend. The results of the experiment supported the hypothesis. The possible implications for the treatment stuttering are discussed.     

Neutralizing sexist titles in Holland's Self-Directed Search: What difference does it make?

Sex-role stereotyping in the linguistic structure of Holland's Self-Directed Search (SDS) was examined. A revised SDS was constructed involving the removal of all masculine-toned terminology from the items and test-taking instructions, as well as the affixing of the letters M/F and F/M to all occupational titles and terms commonly perceived as gender specific. Subjects were 266 lower division female students at a large state university; 133 subjects completed the standard SDS and 133 completed the revised form. Following SDS assessment, subjects rated their inventory with respect to perceived sexual equality. Comparison variables included: daydreams, occupations' scores, summary codes, and subsequent occupational choices. Occupational choices at each stage of the assessment process were classified as nontraditional or traditional choices for women. Results indicated that across all indices derived from the standard and revised versions of the SDS, there were no significant differences in these subjects' performance. The subjects did perceive the two inventories differently, with subjects completing the standard SDS viewing it as slightly less equitable.     

Adult-child discourse: Developmental interaction between information processing and linguistic knowledge

In the present study, the discourse interaction between adult and child was examined in terms of the content of their utterances, and the linguistic and contextual relations between their messages, in order to investigate how children use the information from adults' input sentences to form contingent responses. The analyses described were based on longitudinal data from four children from approximately 21 to 36 months of age. Categories of child discourse, their development and their interactions with aspects of prior adult utterances form the major results of the study. Child utterances were identified as adjacent (immediately preceded by an adult utterance), or as nonadjacent (not immediately preceded by an adult utterance). Adjacent utterances were either contingent (shared the same topic and added new information relative to the topic of the prior utterance), imitative (shared the same topic but did not add new information), or noncontingent (did not share the same topic). From the beginning, the adjacent speech was greater than nonadjacent speech. Contingent speech increased over time; in particular, linguistically contingent speech (speech that expanded the verb relation of the prior adult utterance with added or replaced constituents within a clause) showed the greatest developmental increase. Linguistically contingent speech occurred more often after questions than nonquestions. The results are discussed in terms of how the differential requirements for processing information in antecedent messages is related to language learning.     

Blocking of incidental information in young children

Methods of increasing learning efficiency through a blocking technique were examined in young children. An experimental group of children was trained on an initial task with one relevant dimension, followed by redundancy training in which an incidental dimension also became relevant. A control group given only redundancy training was compared to this group to test how much the experimental subjects blocked or screened out the incidental dimension. In order to increase blocking, three methods were used: a preset transfer problem, an overtraining on the initial task, and a delay following training. The most important finding was increased blocking through the Preset Condition. Overtraining and Delay Conditions had no effect. In addition, more slow learners on the initial task learned about the incidental dimension than fast or intermediate learners. Also, fewer subjects given form on the initial task learned about the incidental dimension than those given color. The Combined Blocking, Delay, and Overtraining group showed partial blocking, while the Preset group demonstrated complete blocking. No developmental differences occurred. The results were interpreted using a modification of Trabasso and Bower's attention model (Attention in learning: Theory and research. New York: Wiley, 1968).     

Positive contrast following gradual and abrupt increases in reward magnitude using delay of reinforcement

In Experiment 1, rats were given a 1-pellet reward for 48 preshift trials. During a subsequent 20-trial postshift phase, one group was shifted to a 12-pellet reward on Trial 1, a second was shifted on Trial 11, and a third was given 1 more pellet each trial and then 12 pellets for the last 10 trials. The speeds of all three groups increased to a level above that of a control group given a 12-pellet food reward throughout training (positive contrast). In experiment 2, rats were shifted from 1 to 12 pellets either gradually or abruptly following either abbreviated training (9 trials) or extended training (20 trials). One group of control subjects received 12 pellets throughout training. The results revealed a positive contrast effect for gradually shifted subjects following extended training but not following abbreviated training. The abrupt shift procedure produced positive contrast following abbreviated training but only a marginal effect following extended training. These results indicate that, contingent upon the amount of preshift training, either gradual or abrupt reward increases may produce positive contrast.     

Psychosocial maturity and interpersonal attraction

Psychosocial maturity (PSM), assessed by scores on the Inventory of Psychosocial Development, was related to interpersonal behavior. In Experiment I PSM and proportion of attitude similarity was varied using Byrne's attraction paradigm in a between-subjects design. The personality variable failed to affect attraction. In Experiment II PSM and proportion of attitude similarity were manipulated in a within-subjects design. High PSM subjects rated the stranger significantly higher in attraction at high levels of similarity and significantly lower in attraction at low levels of similarity when compared to Low PSM individuals. The results were discussed in terms of design differences in personality research and potential mechanisms by which PSM affects attraction (self-esteem and/or competence).     

On the representation of language in the right hemisphere of right-handed people.

Laterality experiments using reaction time were conducted to assess the performance of the right hemisphere of normal people on verbal tasks. The results show that if the task calls for pictorial encoding of visually presented verbal material, then the right hemisphere's performance is superior to that of the left. When the task calls for linguistic analysis, the minor hemisphere displays no aptitude in dealing with the task. The latter finding is at variance with data from split-brain research. To reconcile these differences, it was proposed that language functions, though represented in the right hemisphere of normal people, are functionally localized in the left. When the control which the left hemisphere exerts over the right is weakened or removed, e.g., by commissurotomy, right hemisphere language is released. The application of this model to other neurological phenomena is briefly discussed.     

College Campus Community Readiness to Address Intimate Partner Violence Among LGBTQ+ Young Adults: A Conceptual and Empirical Examination

This paper provides an overview of a conceptual model that integrates theories of social ecology, minority stress, and community readiness to better understand risk for and outcomes of intimate partner violence (IPV) among LGBTQ+ college students. Additionally, online survey data was collected from a sample of 202 LGBTQ+ students enrolled in 119 colleges across the United States to provide preliminary data on some aspects of the proposed model. Results suggested that students generally thought their campuses were low in readiness to address IPV; that is, students felt that their campuses could do more to address IPV and provide IPV services specific to LGBTQ+ college students. Perceptions of greater campus readiness to address IPV among LGBTQ+ college students was significantly and positively related to a more favorable LGBTQ+ campus climate and a greater sense of campus community. Additionally, IPV victims were more likely to perceive higher levels of campus community readiness than non‐IPV victims. There was no association between IPV perpetration and perceptions of campus community readiness. Greater sense of community was marginally and inversely related to IPV victimization and perpetration. Sense of community and LGBTQ+ campus climate also varied to some extent as a function of region of the country and type of institution. Implications for further development and refinement of the conceptual model, as well as future research applying this model to better understand IPV among sexual minority students are discussed.     

Gender Differences in the Association of Intimate Partner Violence and Relationship Values among College Students

Although research has indicated that cognitions and situational factors play a role in relationship satisfaction and aggression, few studies have investigated the association between intimate partner violence (IPV) and relationship values. We addressed this gap by measuring college students’ perpetration of and victimization by four types of IPV; namely, physical violence, sexual violence, threats, and psychological aggression over the past year. One-way ANOVAs and multiple regression analyses were used to measure the association between IPV and the endorsement of relationship values. The results suggest that past IPV perpetration and victimization correlated with the current endorsement of relationship values for males more than females. In general, male perpetrators rated relationship values such as security, investment, others’ approval, and daily conflict as less important than non-perpetrators. Although male victimization explained significant variance in security, investment, and others’ approval, the results were somewhat mixed as to whether victimization related to higher or lower ratings of relationship values, with the majority of the results suggesting an inverse correlation between relationship value endorsement and IPV experience. Future research can investigate mediating factors in the relationship between IPV and relationship value endorsement, as well as look at how IPV and relationship values influence decisions concerning relationship maintenance.
