Psycholinguistic correlations of academic achievement

This research investigated the relationship of the ITPA subtests to measures of academic performance (i.e., the California Achievement Test). Subjects were 137 9-year old children similar to those used in the standardization sample of the 1968 revision of the ITPA. Two kinds of data analyses were undertaken-1. correlation coefficients among the variables were derived, and 2. the subjects were divided into low, average, and high groups based on their CAT performance, and analyses of covariance were run to determine the significance of ITPA differences. The results failed to support the hypothesis that psycholinguistic abilities, except those which contribute to the Grammatic Closure subtest, are related to academic proficiency.     

False physiological feedback and persuasion: Effect of fear arousal vs. fear reduction on attitude change

Two experiments tested the hypothesis that increases in false physiological feedback of fear arousal will enhance persuasion and that reduction in the arousal feedback is unnecessary for increased persuasion to occur. Prior research has usually found a positive relation between level of arousal and persuasion, but support for the drive reduction hypothesis is tenuous. However, Harris and Jellison (1971) claimed support for such a hypothesis. They manipulated subjects' fear arousal cognitively via false physiological feedback while the subjects listened to a persuasive communication. The present experiments used a similar procedure in an attempt to test an "arousal only" against an "arousal reduction" hypothesis. Subjects listened to a persuasive speech while receiving false feedback via a meter concerning their fear arousal. In Experiment I half of the subjects received high arousal and half received moderate arousal information. Within each of these conditions half of the subjects had their arousal reduced, and the other half did not. In Experiment II subjects received either low arousal, high arousal, or high then low arousal feedback while listening. The results of the two studies generally provided support for the "arousal only" hypothesis. An interpretation in terms of Bem's attribution theory was tentatively suggested.     

Effects of task success or failure on causal attributions and person perception

An actor's outcome on a task (success-failure) was manipulated orthogonally to information that the actor either used or did not use drugs. Casual attributions for success-failure were obtained as well as trait ratings of the actor. Subjects read a case study of an artist who either succeeded or failed in his profession. For half of the subjects, the artist was described as using hard drugs, and no mention of drugs was made for. the other half. It was predicted and confirmed that success-failure interacted with drugs-no drugs in determining attributions of ability. It was also found, as expected, that success was attributed to ability and motivation more than was failure. Further, success tended to be internally attributed to the actor, while failure was externally attributed. The interaction obtained for ability attribution was not obtained for a measure of trying, nor for the trait ratings. The results confirmed Kepka and Brickman's (1971) suggestion that ability and motivation are qualitatively different concepts in naive psychology, but some of their specific conclusions are questioned.     

Race versus belief about race as determinants of attraction: Belief prejudice and two kinds of race prejudice

An experiment was conducted to assess the effects of actual racial membership versus similarity of beliefs about racial issues on interpersonal evaluations. Prejudiced and unprejudiced White male students observed a videotaped interaction of two Black and two White male actors discussing racial issues and then evaluated the actors on several scales. One White and one Black actor took a conservative stand on racial issues, and the other White and Black pair of actors took a liberal position. Results from the ratings showed strong belief prejudice effects. Prejudiced subjects were attracted to conservative actors while unprejudiced subjects were attracted to liberal actors. Additionally, there were two kinds of race effects. Prejudiced subjects preferred White to Black actors, but unprejudiced subjects showed a reverse bias, preferring Black to White actors. A tentative explanation for this unusual finding was proposed.     

Communicator credibility and persuasian

Prior research has usually found a positive relationship between a communicator’s perceived credibility and his persuasiveness. An experiment was designed to test the hypothesis that the perceived vested interest of a speaker, the position the speaker advocated, and the social similarity between audience and speaker would influence attributions of credibility and affect the speaker’s persuasiveness. Three variables were manipulated in a 2 by 2 by 2 factorial design. Ss read a speech that either favored (pro) or opposed (con) student voting rights; the speech was attributed to a speaker who was either similar (student) or dissimilar (townie) to the stndent audience and who either had a vested interest (running for elective office) or had no vested interest (merely giving his opinion) :in the position he advocated. As predicted, the similarity of the speaker to the audience, the vested interest of the speaker, and the position advocated in the speech strongly influenced attributions of credibility. However, in contrast to much previous research, persuasion was found to be relatively independent of the variation in the speaker’s perceived credibility. It was suggested that the failure of attributions of credibility to relate to persuasion may have been due to the high degree of ego involvement for the Ss in the topic of student voting rights.     

The effect of change in US quality on the blocking effect

If one CS is paired with a US and then that CS together with a “redundant” stimulus is paired with the US, conditioning of that “redundant” stimulus is attenuated or blocked. The present experiment explores the effect upon this blocking of changing the quality of the US coincident with the introduction of the redundant stimulus. Changing US quality disrupted blocking only when the US potency was also increased. Quality changes in which the redundant stimulus was correlated with a lower potency US only increased blocking. These results are taken as supporting the conditioning model of Rescorla and Wagner but inconsistent with a casual informational model of conditioning.     

Feature Statistics Modulate the Activation of Meaning During Spoken Word Processing

Understanding spoken words involves a rapid mapping from speech to conceptual representations. One distributed feature‐based conceptual account assumes that the statistical characteristics of concepts’ features—the number of concepts they occur in (distinctiveness/sharedness) and likelihood of co‐occurrence (correlational strength)—determine conceptual activation. To test these claims, we investigated the role of distinctiveness/sharedness and correlational strength in speech‐to‐meaning mapping, using a lexical decision task and computational simulations. Responses were faster for concepts with higher sharedness, suggesting that shared features are facilitatory in tasks like lexical decision that require access to them. Correlational strength facilitated responses for slower participants, suggesting a time‐sensitive co‐occurrence‐driven settling mechanism. The computational simulation showed similar effects, with early effects of shared features and later effects of correlational strength. These results support a general‐to‐specific account of conceptual processing, whereby early activation of shared features is followed by the gradual emergence of a specific target representation.     

Changes over time in head and neck cancer patients’ and caregivers’ illness perceptions and relationships with quality of life

Objective: This study investigated changes in illness perceptions from diagnosis to six months later in patients with head and neck cancer (HNC) and their caregivers. The study also examined whether discrepancy in patient and caregiver perceptions at diagnosis predicted patient health-related quality of life (HRQL) at six months.

Design: Forty-two patient–caregiver dyads completed the Brief Illness Perception Questionnaire (Brief IPQ) at diagnosis and again six months later. Patients also completed a HRQL questionnaire at both time points. Analyses were performed using the Actor–Partner Interdependence Model.

Main Outcome Measure: Total patient HRQL assessed by the Functional Assessment of Cancer Therapy (FACT-H&N).

Results: Perceptions of emotional impact and illness concern reduced over time in patients and caregivers. Perceptions of treatment control and identity increased in caregivers only. After controlling for the effects of baseline HRQL, and the individual contribution of patient and caregiver illness perceptions, greater discrepancy in perceptions of timeline, personal control, and illness identity among dyads at diagnosis predicted lower patient HRQL at six-month follow-up.

Conclusion: Patients’ and their caregivers’ perceptions of HNC are dynamic over time. Greater discrepancy between patients’ and caregivers’ illness perceptions at diagnosis predict poorer subsequent patient HRQL.
