The game of the name: An examination of linguistic reference after brain damage

Two aspects of naming have generally been examined in aphasics: the appreciation of a single property of a concept and the ability to use the names of fully elaborated concepts. In applying to aphasics a recently proposed model of semantic organization—one which allows the simultaneous examination of these two aspects—two studies were conducted: Anterior and posterior aphasics were asked (1) to name members of superordinate categories, their responses being converted into prototypicality scores (the degree to which a member of a category resembles an ideal member of that category) and (2) to differentiate between more or less prototypical members of a category and their superordinates. The results revealed that, while anterior and posterior aphasics differ in their use of the names representing fully elaborated concepts, these groups show no differences in terms of the appreciation of a single property of a concept. The implications of these findings for reference were discussed.     

Memory for pure and verb-derived nouns: implications for hemispheric specialization

Memory for pure and verb-derived nouns was assessed in two long-term memory experiments. The two types of nouns were matched for word frequency and number of syllables. The results of both experiments indicated that pure and verb-derived nouns do not differ in their demands on the information processing capacities of normal subjects when confounding factors are controlled. The implications of these findings for studies of hemispheric specialization for language are discussed.     

A structural determinant of hemispheric processing of pictorial material

A qualitative difference of processing type by the two cerebral hemispheres was demonstrated in a picture arrangement task which involved a concept of temporal sequence. Half the sequences were designed to rely on analytic categorical processes and half on configurational processes. The subjects were patients with unilateral hemispheric damage of vascular etiology. Using two measures of performance, latency and errors, patients with right hemisphere damage were seen to be relatively impaired on those sequences designed to employ hypothesized right hemisphere (configurational) processing and patients with left hemisphere damage were seen to be relatively impaired on those sequences designed to employ hypothesized left hemisphere (categorical) processing.     

Toward the analysis of close relationships

Two central questions are addressed: (1) How does one distinguish among relationships differing in closeness at any single point in time? (2) How do relationships change over either a short or a long time span? The first question suggests looking inside the Person-Other “intersection.” Findings from several empirical studies are described. The second question leads to discussions of short-term and long-term temporal processes. Regarding long-term pair processes, it is proposed that research can be stimulated by recognizing a five-phase sequence which extends from (a) initial attraction, to (b) building a relationship, (c) continuation, (d) deterioration, and (e) ending; transitions between adjacent phases are considered. The importance of theoretical models is emphasized throughout.     

Integrating information across eye movements

A series of experiments was conducted in which a word initially appeared in parafoveal vision, followed by the subject's eye movement to the stimulus. During the eye movement, the initially displayed word was replaced by a word which the subject read. Under certain conditions, the prior parafoveal word facilitated naming the foveal word. Three alternative hypotheses were explored concerning the nature of the facilitation. The verbalization hypothesis suggests that information acquired from the parafoveal word permits the subject to begin to form the speech musculature properly for saying the word. The visual features integration hypothesis suggests that visual information obtained from the parafoveal word is integrated with foveal information after the saccade. The preliminary letter identification hypothesis suggests that some abstract code about the letters of the parafoveal word is stored and integrated with information available in the fovea after the saccade. The results of the experiments supported the latter hypothesis in that information about the beginning letters of words was facilitatory in the task. The other two hypotheses were disconfirmed by the results of the experiments.     

Recognition memory for objects in very young children: The effect of shape and label similarity on preference for novel stimuli

In two studies, 88 children 12 to 38 months of age were briefly shown 24 common objects on familiarization trials. On subsequent test trials, these objects reappeared paired with novel objects. On one-third of the test trials pairs were similar in shape, on another third of the test trials pairs shared a common label, and on the remaining test trials pairs were unrelated. Looking times for each of the two objects on test trials were measured. All but the youngest age group showed significantly longer looking times for novel than for familiar objects for all three kinds of test pairs. However, for 19- to 31-month-olds preference for novel stimuli in the common Label Condition, although significant, was less than preference for novel stimuli when shape was similar or when unrelated stimuli were paired. Recognition in the oldest group was unaffected by condition. The results suggest a developmental period during which label or conceptual similarity has a special significance for recognition, and are discussed within theoretical frameworks concerning the very young child's developing semantic and categorization skills.     

Grammatical class effects in relation to normal and aphasic sentence processing

Agrammatic, Broca's aphasic patients, Wernicke's aphasic patients, and neurologically intact control subjects were asked to detect target letters in prose passages and in a scrambled word passage. The targets were embedded, in some instances, in content words (open-class vocabulary items), and in other instances, in function words (closed-class vocabulary items). With respect to the prose passages, both the control subjects and Wernicke's aphasic patients were more apt to notice target letters when they appeared in the open-class items than when in closed-class items; by contrast, the agrammatic Broca's patients showed no vocabulary class detection difference. The Wernicke's patients were not entirely normal, however: Whereas the normal subjects showed a much smaller vocabulary class effect for letter detection in the scrambled condition, the Wernicke's maintained the pattern they had shown in the prose condition. These and other findings obtained on the letter cancellation task are discussed in relation to lexical access mechanisms geared to sentence parsing.     

Integrative bargaining in a competitive market

The behavioral decision theory literature was used to identify the determinants of negotiation success in an integrative bargaining, free-market exercise. This study provides a novel methodology for studying negotiation. Specifically, buyers and sellers were allowed to engage in negotiations with as many competitors as possible in a fixed time period. The results suggest that integrative bargaining behavior increases and the market converges toward a Nash equilibrium as negotiators gain experience. In addition, the results suggest that (1) positively framed negotiators (“What will be my net profit from the transaction?”) complete more transactions than negatively framed negotiators (“What will be my expenses on this transaction?”), (2) negotiators who are given moderately difficult profit constraints in order to be allowed to complete a transaction achieve more profitable transactions than negotiators without such constraints, and (3) both framing and the existence of constraints affect the total profitability of the negotiator.     

Cognitive biases in blaming the victim

Past research on cognitive biases has demonstrated the existence of a hindsight effect, whereby the receipt of outcome knowledge increases the perceived likelihood of the reported event. Three experiments were conducted that tested and supported the hindsight effect as a cause of victim blaming. Subjects read detailed accounts that were identical except for the concluding sentence, which provided outcome information. Half the subjects in each experiment were informed that the woman narrating the account was raped; the other half read a neutral outcome. Experiment 1 demonstrated that subjects were unable to ignore the influence of outcome knowledge, leading to an exaggerated perception of how likely the outcome appeared. In Experiment 2, the woman was blamed more by subjects who read the rape outcome than by those who read the neutral outcome, despite the presentation of identical behaviors and personality traits prior to outcome information. The increased blame attributed by rape outcome subjects was behavioral, and not characterological, in nature. Experiment 3 found a direct association between the hindsight effect and victim blaming and also demonstrated that an attempt to reduce the negative impact of the hindsight effect on victim blaming was ineffective due to the salience of the rape outcome. Explaining how a neutral outcome was possible given the same account did not reduce victim blaming by subjects who received a rape outcome. Rather, those who received a neutral outcome increased their victim blaming when asked to explain a rape outcome. The implications for victims are discussed.
