The Influence of Phonological Context on the Sound Errors of a Speaker with Wernicke's Aphasia

A corpus of phonological errors produced in narrative speech by a Wernicke's aphasic speaker (R.W.B.) was tested for context effects using two new methods for establishing chance baselines. A reliable anticipatory effect was found using the second method, which estimated chance from the distance between phoneme repeats in the speech sample containing the errors. Relative to this baseline, error-source distances were shorter than expected for anticipations, but not perseverations. R.W.B.'s anticipation/perseveration ratio measured intermediate between a nonaphasic error corpus and that of a more severe aphasic speaker (both reported in Schwartz et al., 1994), supporting the view that the anticipatory bias correlates to severity. Finally, R.W.B's anticipations favored word-initial segments, although errors and sources did not consistently share word or syllable position.     

I'm Mad as Hell,and I'm Not Going to Take It Anymore: Reports of Negative Emotions as a Self‐Presentation Tactic1

This research investigated how self‐presentation goals can influence public expressions of negative emotions. In Study 1, participants were asked how individuals would present their negative emotions if they were trying to create each of 5 different impressions, which corresponded to 5 self‐presentation strategies identified by Jones and Pittman (1982). Results show that individuals were expected to systematically understate or exaggerate their negative emotions, depending on the impression/strategy. In Study 2, participants discussed with another person a course they were taking where they were not doing as well as they had hoped. They were instructed either to present their feelings honestly, to ingratiate, or to intimidate the other person. Compared to the honesty condition, ingratia‐tion led to fewer negative emotions being expressed, whereas intimidation led to more negative emotions being expressed. Taken together, these studies provide initial evidence about when and how self‐presentation motives can influence reports of negative emotions.     

Ontogeny of early event memory: I. Forgetting and retrieval by 2- and 3-month-olds

In 2 experiments, 2-month-olds, trained in the mobile conjugate reinforcement paradigm for two daily sessions, showed retrieval deficits relative to 3-month-olds. In Experiment 1, tests of simple forgetting administered to 2-month-olds after retention intervals of 1, 3, 6, and 9 days (a period over which 3-month-olds remember the contingency) indicated that their forgetting was complete after delays greater than 1 day. In Experiment 2, reactivation treatments administered to 2- and 3-month-olds alleviated forgetting after a retention interval of 28, but not 35, days in the 3-month-old group only. Previously, alleviated forgetting by a reactivation treatment had been demonstrated in 2-month-olds after a delay of 18 days. In both of the present experiments, performance of the two age groups did not differ during the immediate retention test at the end of training. These results suggest that neither the age of the infant nor the age of the memory determines memory retrieval after long delays; instead, it appears to be determined by the length of time that a memory has been inaccessible (i.e., forgotten). We propose that factors which delay simple forgetting will correspondingly increase the length of the interval over which a retrieval cue can still be effective in a reactivation paradigm, irrespective of the age of the infant or the age of the memory.     

A psychological pulse train: how young children use this cognitive framework to structure simple rhythms

Summary This paper examines the reproduction of both regular rhythms and irregular sequences by 5- and 7-year-old children, concentrating on the important role played by their organization around a pulse train. It is shown that: (a) the closer rhythms are to a regular beat the easier they are to reproduce and the greater are the improvements with age; (b) memory capacity is limited by the number of pulses around which the rhythm is organized rather than by the number of elements it contains; (c) all the children's productions contain two interval lengths that are in a ratio close to 1:2 and arranged in preferential sequences which we have called stereotypes; (d) arrhythmic sequences can only be reproduced if the intervals undergo a systematic distortion towards regularity. These results are interpreted in relation to a pulse-train hypothesis which states that on hearing a rhythm an internal clock or time base is evoked around which the rhythm is structured.     

Attitudinal and Normative Factors as Determinants of Gay Men's Intentions to Perform AIDS-Related Sexual Behaviors: A Multisite Analysis1

The purpose of this study was to test the applicability of the theory of reasoned action as a basis for understanding and predicting gay men's intentions to perform AIDS-related sexual behaviors. A total of 314 self-identified gay or bisexual men from Seattle, Denver, and Albany participated in the study. They were asked to indicate their intentions to perform 15 specific sexual behaviors chosen to represent different degrees of risk of contracting AIDS or other sexually transmitted diseases. In addition, they were asked to respond to items measuring the attitudinal and normative considerations regarding each behavior. As expected, the results showed that the gay men's intentions were significantly predicted by the two factors. More interesting, it was found that, although attitudes are consistently the more important determinants of intentions for all the respondents, the importance of normative considerations varies across cities. This difference in normative considerations is interpreted in light of the differences in the structure of the three gay communities. Implications for designing sample-specific intervention programs are discussed.     

DEFINING,VALIDATING, AND INCREASING INDICES OF HAPPINESS AMONG PEOPLE WITH PROFOUND MULTIPLE DISABILITIES

In this study we attempted to operationalize, measure, and increase happiness among people with profound disabilities. Happiness indices were defined and observed among 5 individuals. Validation measures indicated that (a) increases in happiness indices were observed when individuals were presented with most preferred stimuli relative to least preferred stimuli, (b) increases in unhappiness indices were observed when they were presented with least preferred relative to most preferred stimuli, and (c) practitioner ratings of participant happiness coincided with observed indices. Subsequently, classroom staff increased happiness indices through presentation and contingent withdrawal of activities. Results suggested that a behavioral approach can enhance happiness as one aspect of quality of life among people with profound disabilities. Research directions are offered that focus on using a behavioral approach to investigate other private events that are important among people with disabilities.     

The Development of Coping Resources in Adulthood

ABSTRACT We examined three community samples to determine whether stressful episodes form a context for the development of coping resources in adulthood. The first study found that 81.9% of a sample of 845 older men reported drawing upon prior experiences in coping with a recent problem. Content analysis revealed that only 22.7% drew upon similar stressful episodes; the rest drew upon problems from work, the military, illnesses, deaths, etc. The second study replicated the earlier findings in 102 men and women, ages 24 to 84, who reported on a recent low point in semistructured interviews. In addition, 75% reported long-term effects, equally split between negative, positive, and mixed effects. Those individuals who perceived advantages from the low point were significantly more likely to report positive long-term effects. The third study replicated the findings from the first two studies in a sample of 941 men and women ages 23 to 62. Path analyses showed that coping strategies differentially predicted perceived positive or negative outcomes, which in turn predicted current mastery and depression levels. While the findings are cross-sectional and causality cannot be inferred, they are nonetheless supportive of the effects of stress and coping on personality.     

FUNCTIONAL EXPLANATIONS AND NATURAL NORMS

In this paper, I try to develop an account of functions which might be of use to a biologist engaged in classifying and explaining natural phenomena. The most pressing difficulty facing such an account is the need to reconcile the normativity of function statements with their explanatory force. I consider two familiar accounts of function statements, offered by Andrew Woodfield (an ‘Actual Capacity Theorist’) and Larry Wright (a ‘Historical Theorist’). I examine both accounts in search of the strongest possible formulation of each type of theory. I fail to find a formulation of the ACT which is completely immune from counterexamples, but I do find a satisfactory formulation of the HT. In particular, I argue that the HT should incorporate a point central to the ACT that functions involve a means/end relationship between two devices. I then consider functional explanations: I argue that an ACT which holds that function statements are intrinsically explanatory cannot offer a satisfactory account. The account offered by Woodfield, who rejects this assumption, is adequate, though less attractive than the account suggested by the HT. I conclude by considering how the HT can account for functional norms.     

VERY LONG-LASTING PRIMING IN PICTURE NAMING

Abstract— A form of long-lasting repetition priming has been demonstrated by faster naming of pictures repeated from a prior exposure than new pictures. This facilitation is independent of explicit memory in both normal subjects (Mitchell & Brown, 1988) and amnesic patients (Cave & Squire. 1992). Using picture naming, the current study demonstrated that priming could be detected with delays of between 6 and 48 weeks between the initial exposure and the priming test. Recognition memory was also above chance at these delays, but performance on the two tests appeared independent. These results show that a single stimulus exposure can have very long-lasting effects. Accounts of repetition priming as a form of implicit memory will have to accommodate long-lasting changes in stimulus processing based on a single exposure.
