Motivation concepts and sexual identity

The association dimension of the Picture Identification Test (PIT) was used to investigate the motivation concepts of male and female university students classified as Declared Homosexual, Sexually Uncertain, Clinical Control, and Normal Control. The t test was used to identify Need Association Dyads which discriminated (p < .01) groups. Greater than chance numbers of variables discriminated each of the pairs of groups within each sex except the Sexually Uncertain versus Clinical Control Male groups, the Declared Homosexual versus Clinical Control Female groups, and the Declared Homosexual versus Normal Control Female groups. PIT Need Association Dyads were discussed as a type of implicit personality theory assessment with emphasis on the beliefs subjects hold about the simultaneous expression of needs.     

A comparison of the environments of day care centers and group day care homes for 3 year olds

Caregiver-child interaction and social participation were compared in community-based day care centers and group day care homes for three year olds. Use of group day care homes made it possible to control for group size and adult-child ratio. Day care homes were found to be more structured in terms of curriculum, and more flexible in terms of overall schedule and social-emotional climate. Adult child interaction was of higher quality during structured periods in day care homes. Social participation was of higher quality in day care homes. The adult-child interaction in both types of day care was impersonal and neutral in affective tone.     

Conditioned fear-induced opiate analgesia on the Formalin test: Evidence for two aversive motivational systems

Fear, conditioned to apparatus cues associated with electric shock, was measured by recording freezing. Pain reactivity was simultaneously measured by recording the paw-licking and paw-lifting response to Formalin injected into a paw. Stimuli associated with shock produced freezing and inhibited the responses to Formalin; whereas various control stimuli did neither. These results indicate that one of the responses to fear is analgesia. The opiate antagonist naltrexone reversed this analgesia, suggesting that the analgesia has an opiate nature. The results were interpreted in terms of a two-aversive-motivational-systems model. One system, the pain system, is instigated by tissue-damaging stimuli and produces recuperative behavior that functions to promote healing. The other system, the fear system, is triggered by conditioned fear stimuli. It produces species-specific defensive reactions and also inhibits the pain system via analgesia.     

A conditional logit model of collegiate major selection

The choice of a major by a college student is viewed as depending upon the quantity of various outputs (such as income and status) each major provides and the taste structure of the student for these outputs. Tradeoffs in outputs occur so that high status may overcome low-income potential in the occupation into which the major provides entry. Different taste structures among students mean tradeoffs occur at different rates, so that taste structues are best associated with student major selection in a probability sense. Changes in the probability of selecting a collegiate major are associated with changes in student taste structures via a conditional logit model. The taste structure of a student is hypothesized to depend upon the environment in which the student was raised and the environment in which the student now lives. The relationship between environment and taste is also best stated in a probability sense and a second logit model is used to describe this relationship. Estimation of the two logit models, using survey data, attempts to quantify the hypothesized route from environment to taste structure to major selection for entry into an occupation. An example of this route is the finding that women students place more importance on obtaining high income than do men students and the greater the importance of high income, the lower the probability of selecting an education major, the greater the probability of selecting a humanities or social science major. Other results of estimation are presented and discussed.     

Word age-of-acquisition and lexical decision making

This paper reports two experiments concerning the effects of word age-of-acquisition and other word attributes on speed of lexical decision. Analyses of group average data indicated that word length, frequency and familiarity were the major determinants of decision speed. Previous reports of age-of-acquisition effects on lexical decision are attributed to failures to control for word familiarity.     

Conditioning of counter-empathetic emotional responses

The present research tested the hypothesis that the quality of an observer's vicarious emotional response, as measured by autonomic, expressive, and self-report indexes, is a function of the observer's conditioning history with particular facial expressive displays of emotion. It was predicted that conditions of congruence (Symmetry) between the affective expression of a model and the outcome (shock or reward) presented to an observer would enhance initial empathetic responses, but that conditions of incongruence (Asymmetry) between the model's displays and observer's outcomes would lead to counter-empathetic responses. These changes in the quality of observers' vicarious emotional responses should generalize to a test phase when no rewards or punishments are presented to observers. The results for all measures were consistent and indicate that asymmetric conditioning modified the initial empathetic responses of observers to either counter-empathetic responses or indifference. On the other hand, symmetric conditioning enhanced observers' initial empathetic responses. These effects were evident in the test phase when no reinforcements were administered to the subject. The results are consistent with the theoretical assumption that facial expressions of emotion can acquire meaning and hedonic valence because of their predictive significance and thus can function as conditioned stimuli capable of evoking empathetic and counter-empathetic emotional responses.     

Self-focused attention and belief perseverance

The perseverance of an erroneous belief was investigated in the debriefing paradigm as a function of self-focused attention. Subjects were given either success or failure experiences via bogus performance feedback and received this feedback under high or low mirror self-focusing. All subjects were subsequently debriefed about the false nature of the feedback, and then, before answering questions about their estimated actual performance and ability, mirror self-focus was again manipulated. The results showed that self-focus prior to debriefing increased belief perseverance while self-focus after debriefing reduced the perseverance effects. Discussion of these findings emphasized the role of self-focus in information processing before and adherence to veridical standards after debriefing.     

Teaching autistic children to use extra-stimulus prompts

Autistic children often do not transfer from extra-stimulus prompts, and thus do not utilize a frequent learning aid. It has been hypothesized that this is due to stimulus overselectivity; a failure to respond to simultaneous multiple cues. This study was designed to determine if autistic children who initially respond only to single cues can be taught a set to respond to two cues and subsequently utilize an extra-stimulus (pointing) prompt. Four autistic children were pretested to determine if they could learn a complex visual discrimination by either trial and error or an extra-stimulus prompt fading procedure. Since they did not, the children were then taught to respond to two cues through a multiple-cue training procedure and subsequently tested to determine if they could now utilize a pointing prompt. Results indicated that while all four children initially did not transfer from an extra-stimulus (pointing) prompt, they did so subsequent to multiple-cue training. The results are discussed in terms of implications for treatment (remediating overselectivity) and in relation to normal child development.     

Reading and listening comprehension in Broca's aphasia: Lexical versus syntactical errors

Ten agrammatic Broca's aphasics were presented with a series of four picture plates together with a spoken or written sentence stimulus. All sentence stimuli were of the structure, the + N + is/are + V + ing + the + N. The four pictures on each stimulus plate represented (a) the correct response, (b) a reversal of the stimulus sentence subject and object, (c) a change in the number of the subject of the stimulus sentence, and (d) a change in one of the major lexical items of the stimulus sentence. Subjects selected the correct picture most often. When they erred, they usually selected a subject-object reversal. Number errors were less frequent, and the patients seldom selected a change in major lexical item. This pattern occurred with both written and spoken sentences. These results were interpreted as reflecting the dependence of agrammatic Broca's aphasics on the semantic interpretation of the lexicon for decoding sentences in the face of deficits in syntactical-grammatical interpretation, irrespective of comprehension modality.     

Cognitive and behavioral self-control strategies: Applications for the clinical management of adult stutterers

A model of therapy for adult stutterers which emphasizes the role of cognition in mediating the conditions for behavioral change is described. The philosophy of the program along with the specific forms and effects of several self-control strategies are discussed in relation to: (1) expectancy formation and the attainment of goals; (2) speech modification procedures; (3) transference of clinical gains; and (4) assessment of results. The use of cognitive restructuring procedures, self-instructional strategies, imagery and other coping skills for the management of speech-related stress is outlined. The importance of developing self-management and self-monitoring programs that clients may use in ongoing confrontations with real-life problems is emphasized in defining responsible behavior and the responsibility for change.
