Language lateralization in English-French bilinguals

Forty English-French bilinguals divided into equal numbers of nonfluent and fluent subjects took part in a dichotic listening test involving both intralingual and interlingual conditions. No difference in lateralization was found between primary and secondary language in either condition. In the intralingual condition, however, fluent bilinguals showed a significantly lower right ear advantage than did their nonfluent counterparts. In the interlingual condition, French-dominant subjects were found to be more ambilateral than English-dominant subjects, while both groups tended to respond preferentially to French words. These results suggest that growing bilingual proficiency does increase left ear/right hemisphere participation, but in intralingual situations only. Moreover, when both languages are contrasted, French appears to be more salient than English.     

Hemisphere dynamics in lexical access: automatic and controlled priming

Hemisphere differences in lexical processing may be due to asymmetry in the organization of lexical information, in procedures used to access the lexicon, or both. Six lateralized lexical decision experiments employed various types of priming to distinguish among these possibilities. In three controlled (high probability) priming experiments, prime words could be used as lexical access clues. Larger priming was obtained for orthographically similar stimuli (BEAK-BEAR) when presented to the left visual field (LVF). Controlled priming based on phonological relatedness (JUICE-MOOSE) was equally effective in either visual field (VF). Semantic similarity (INCH-YARD) produced larger priming for right visual field (RVF) stimuli. These results suggest that the hemispheres may utilize different information to achieve lexical access. Spread of activation through the lexicon was measured in complementary automatic (low probability) priming experiments. Priming was restricted to LVF stimuli for orthographically similar words, while priming for phonologically related stimuli was only obtained in the RVF. Automatic semantic priming was present bilaterally, but was larger in the LVF. These results imply hemisphere differences in lexical organization, with orthographic and semantic relationships available to the right hemisphere, and phonological and semantic relations available to the left hemisphere. Support was obtained for hemisphere asymmetries in both lexical organization and directed lexical processing.     

Impaired ranking of semantic attributes in dementia

The present work explored the loss of semantic attributes that is said to occur in dementia. In the first two experiments, subjects had to select attributes that went with concepts like airplane and church. The finding that demented subjects maintained high levels of accuracy when selecting attributes suggested that the semantic content of their concepts was relatively well preserved. The organization of the content was explored in a third experiment by having subjects order attributes according to their relative importance in defining concepts. While demented subjects performed better than chance, they did not rank attributes as well as healthy aged subjects, suggesting a disruption in organization whereby the importance of central attributes is reduced. The hypothesized disruption in organization is viewed in relation to the learning and memory deficit that is the hallmark of the dementias.     

Layoffs,self-esteem,and survivor guilt: Motivational,affective, and attitudinal consequences

The present study explored the effect of layoffs on the subsequent productivity of “survivors”. All participants performed a proofreading task either after witnessing the dismissal of a co-worker (Layoff condition) or not (No-Layoff condition). Consistent with equity theory, the quantity of workers' performance was greater in the Layoff than in the No-Layoff condition. A Worker Self-Esteem × Layoff interaction effect revealed that the Layoff effect was entirely attributable to the low, rather than the medium or high, self-esteem participants. Additional analyses revealed that the layoff caused participants to (1) experience increased feelings of remorse and (2) develop more negative attitudes toward their co-worker, both of which are also consistent with equity theory. Practical and theoretical implications are discussed.     

The effectiveness of imagery and sentence strategy instructions as a function of visual and auditory processing in young school-age children

The relationship between auditory and visual processing modality and strategy instructions was examined in first- and second-grade children. A Pictograph Sentence Memory Test was used to determine dominant processing modality as well as to assess instructional effects. The pictograph task was given first followed by auditory or visual interference. Children who were disrupted more by visual interference were classed as visual processors and those more disrupted by auditory interference were classed as auditory processors. Auditory and visual processors were then assigned to one of three conditions: interactive imagery strategy, sentence strategy, or a control group. Children in the imagery and sentence strategy groups were briefly taught to integrate the pictographs in order to remember them better. The sentence strategy was found to be effective for both auditory and visual processors, whereas the interactive imagery strategy was effective only for auditory processors.     

The role of need level and/or need salience as moderators of the relationship between need satisfaction and work alienation-involvement

Contrary to previous findings documenting the importance of higher-order need satisfaction, a recent study by G. J. Gorn and R. N. Kanungo (Organizational Behavior and Human Performance, 1980, 26, 265–277) has indicated that satisfaction of lower-order needs may lead to job involvement if such needs are salient. Data from a heterogeneous sample of 632 employees from six organizations were used to test six hypotheses concerning the effects of need level (higher vs lower order) and need salience as moderators of the relationship between need satisfaction and alienation-involvement. Three different ways of operationalizing need saliency were used, including a replication of Gorn and Kanungo's procedure. Higherorder need satisfaction was correlated with alienation-involvement scores to a significantly greater degree than was lower-order need satisfaction, even for those for whom lower-order needs were most salient. Need saliency was not found to moderate the need satisfaction-involvement relationship when need level was controlled. Issues regarding the operationalization of “need salience” were discussed and a new measure of alienation-involvement (the A-I Scale) was introduced. Implications for further empirical investigations of the need saliency issue were noted, as was the universal application of job enrichment programs aimed at promoting higher-order need satisfaction.     

The impact of career exploration and interview readiness on interview performance and outcomes

In a longitudinal study of 78 graduate business students, three aspects of career exploration—environment exploration, self-exploration, and the amount of information acquired—were examined as predictors of interview performance (interview rating and self-rating) and outcomes (call-back interviews and job offers). Environment exploration and the amount of information acquired related significantly with the recruiter's rating of interview performance and interview outcomes; self-exploration correlated with the recruiter's rating of interview performance. Interview readiness variables (perceived past performance, verbal persuasion, and feelings of self-efficacy) correlated modestly with career exploration variables, interview performance ratings, and interview outcomes.
