Contextual control of the extinction of conditioned fear

Rats received 15 pairings of a CS and shock in one context, and then a series of CS-alone trials in a second context. Even though this extinction procedure produced a complete loss of conditioned suppression, when the animals were returned to the site of original conditioning, suppression was renewed to a level comparable to that of animals that had not undergone extinction. Controls indicated that the renewed suppression was not due solely to pseudoconditioning, suggesting that the CS-US association had survived extinction. Renewed suppression was also demonstrated in a third context that was never associated with shock. Loss of suppression did not necessarily depend upon inhibitory conditioning of the extinction context. The data suggest that extinction of conditioned fear is specific to the context in which it occurs. They also suggest the possibility that animals might discriminate episodes in which a CS is reinforced and nonreinforced independently of the excitatory or inhibitory status of cues, like contextual stimuli, that are coincidentally present during those episodes.     

Conditions under which thurstone case III representations for binary choice probabilities are also Fechnerian

By a Thurstone Case III representation for binary symmetric choice probabilities P_x,y we mean that there exist functions F, μ, σ > 0 such that $\text{P}{}_{\mathrm{x,y}}\text{= F[}\text{(μ(x) ? μ(y))}\text{(σ}{}^2\text{(x) + σ}{}^2\text{(y))}{}^{\mathrm{<mtext>1</mtext><mtext>2</mtext>}}\text{]}$. We show that the constraint σ = constant, or μ = ασ + β, α ≠ 0, is both necessary and sufficient for a Thurstone Case III representation to be Fechnerian, i.e., to be reexpressable as as P_x,y = G(u(x) ? u(y)) for some suitably chosen functions G, u.     

Some correlates of stuttering severity judgments

Thirteen adult male stutterers recorded the Amplifier Passage on high-quality audiotape. One sentence from each recording was paired with one sentence from each of the remaining 12 recordings. The resulting 78 sentence pairs were presented to eight speech-language pathologists who were asked to judge which stutterer in each pair was more severe and to rate the confidence of each of these judgements. The confidence ratings were analyzed by means of the individual differences model of multidimensional scaling. The results suggested that reading rate and the number of intrasentence pauses were important parameters in determining the severity of stuttering.     

Dichotic listening in a child recovering from acquired aphasia

A right-handed 6-year-old boy with acquired aphasia of left-hemisphere origin was investigated with various dichotic listening tasks 8 and 13 months after onset of the symptoms. Total right ear extinction was found repeatedly using both numbers and words as stimuli. Furthermore, magnitude of right ear extinction was not amenable to modification through verbal training, but disappeared when words were presented to the child's right ear with simultaneous white noise to the left ear. The findings are discussed in terms of the plasticity of cerebral dominance during childhood.     

Construct validity of four basic Vocational Interest factors

To find evidence of the generalizability of four interest factors established for tests within the Roe-Holland framework, factor scores derived from a Vocational Interest Inventory grounded in Roe's system were correlated with the empirically based Strong-Campbell Occupational scale scores. For this sample of 300 counseling clients, a majority of the hypothesized relations were found, and arranging the occupations along these bipolar dimensions both sharpened the definitions of the factors and provided an additional interpretive aid for counseling.     

Personological dynamics of leadership

This study reports on the personality correlates of rated leadership using the California Psychological Inventory (CPI) and 50 college football players. Subjects were also given leadership scores using a CPI-based leadership regression equation. Two findings are of interest. First, consistent with past research, leaders were characterized by high scores on CPI Scales for Dominance, Self-Acceptance, and Responsibility. Second, coaches' leadership ratings correlated .62 with scores on the leadership regression equation. This provides an additional cross validation of this leadership equation and supports the notion that a stable set of personality traits characterize leaders. Some theoretical implications are discussed.     

Unclogging the bogus pipeline: A critical reanalysis of the Cherry,Byrne, and Mitchell study

The assignment of subjects to conditions on the basis of social desirability scores could not have been done in the manner described by Cherry, Byrne, and Mitchell (Journal of Research in Personality, 1976, 10, 69–75). Even if subject assignment procedures were not challenged the data do not support the authors' conclusions. Additional statistical analyses were carried out to test the hypotheses of the original study. It is concluded that either the demand cue manipulation was not successful or else paper-and-pencil and bogus pipeline measurement procedures are equally reliable measurement devices for the attitude similarity effect.     

The sentence-verification paradigm: A case study of two conflicting aproaches to individual differences

The contrasting approaches of differential psychology and cognitive psychology to the same individual differences data are outlined. Using illustrative data from the Clark and Chase (1972) sentence-picture verification task, four loci of conflict between these two disciplines are identified. These areas of conflict center around issues of (1) theory versus measurement, (2) meaningfulness versus reliability, (3) linearity of relationships, and (4) discontinuities in performance. We conclude on the basis of observed incompatibilities that a simple derivation of differential psychology from cognitive psychology is not likely, but separate development of complementary theories may be possible.     

Differential methods of causal attributions for strangers vs acquaintances

Previous research has demonstrated that people are more likely to attribute a stranger's behavior to external causes if that behavior is common in a given population than if it is relatively unique (the consensus rule). It was proposed in the present paper that another and perhaps simpler rule is available for causal attributions for an acquaintance's behavior, such that more external attributions are made as the behavior becomes increasingly inconsistent with extant impressions of the target (the goodness-of-fit rule). It was found that the goodness-of-fitrule, but not the consensus rule, was used in the attribution of causality for acquaintances when the behavior could be made to fit with extant impressions. When the behavior was completely inconsistent with extant impressions, both consensus and goodness-of-fit rules were used, such that the most external attributions were made in the poor fit/high consensus condition.
