Lexical Representation and Processing of Morphologically Complex Words: Evidence from the Reading Performance of an Italian Agrammatic Patient

The study of patients with acquired language disorders has provided crucial evidence for contemporary theories on mental lexical representation. This is particularly true for the representation of morphologically complex words. In this paper we analyzed the performance of a patient (M.B.) affected by agrammatism and dyslexia. M.B. was required to read aloud simple and morphologically complex words. The patient's pattern of errors was interpreted as the result of a predominant use of the lexical routine (phonological dyslexia). Three reading tasks were developed which allowed us to test M.B.'s ability to read morphologically complex words (reading of regular and irregular plurals; reading of high- and low-frequency singular and plural nouns; reading of evaluative suffixes). Errors were determined by frequency effect rather than by type of suffix (i.e., inflectional or derivational). High-frequency morphologically complex items seemed to meet stored representations, thus avoiding the parsing procedures that are required for less frequent items. These results are in keeping with dual route models of lexical representation of morphologically complex words.     

Bringing the Organization into Organizational Research: An Examination of Academic Research Inside Organizations

One common suggestion for reducing the gap between research and practice is for academics to conduct more of their research in real organizational settings. However, there is considerable skepticism among academics about the willingness of organizations to open their doors to researchers, and among both academics and practitioners about the potential value of doing so. The present study examines how 141 successful academic research projects in real organizations proceeded from start to finish. Our results suggest that organizations may be more open to academic research than is commonly believed, and that most researchers experience few problems with participating organizations. On the other hand, most of the examined projects were not heavily collaborative, and only half of the researchers maintained organizational contact after the research was completed. Based on our findings, we offer suggestions for researchers wishing to do organizational research as well as for their organizational partners.     

The Relationship Between Agentic and Communal Personality Traits and Psychosocial Adjustment to Breast Cancer

Agency, communion, unmitigated agency (UA), and unmitigated communion (UC) are related to psychosocial health outcomes in nonclinical and medical populations. This study examined the relationship between these personality traits and emotional and interpersonal well-being, as up to 50% of women experience difficulties in psychosocial adjustment after being diagnosed with breast cancer. Seventy-four women newly diagnosed with breast cancer completed baseline assessment measures within 2 weeks prior to their first chemotherapy treatment or at the beginning of their hormonal therapy. Findings indicate that (1) agency and UA are important correlates of emotional and interpersonal adjustment and should be considered when attempting to identify women at high risk for psychosocial distress, and (2) UC deserves increased attention in behavioral medicine research, given its strong relationship with emotional distress in a breast cancer population. Thus, evidence continues to accumulate regarding the important relationship of these personality traits to psychosocial outcomes in medical populations.     

Females in charge: Effects of sex of subordinate and romantic attachment status upon self-ratings of dominance

Female, male, and mixed-sex dyads in which one member was assigned the leader role interacted and rated their own dominance throughout the interaction. The effects of gender and romantic attachment status (whether one has an exclusive dating partner or is “unattached” and free to go out with someone new) upon these self-ratings of dominance within the interaction were examined. The results showed that both leaders and subordinates perceived female leaders to be less dominant than male leaders. In addition, members of mixed-sex pairs rated themselves as less dominant than did those in same-sex pairs. Female leaders paired with males rated themselves least dominant and unattached female leaders interacting with males rated themselves least dominant of all. Female subordinates rated themselves as less dominant when with male leaders than when with female leaders, while the effect of the gender of the leader was insignificant for male subordinates. The results are discussed as evidence of a role conflict created by the contradictory roles of “dominant” leader and “subordinate” female, roles described by the sex role stereotypes prevalent in our culture.     

Production of narrative and procedural discourse in aphasia

The study described the abilities of a group of 10 aphasics and 10 normals to produce narrative and procedural discourse. The experimental tasks included telling stories, producing summaries, giving morals to the stories, and producing procedures. The variables examined in the investigation included features of sentential grammars, such as amount of embedding, and features of discourse grammars, such as occurrence of elements of superstructure in narrative. Additionally, raters assessed the content and clarity of the discourses. The results showed that aphasics produced well-structured narrative and procedural discourse. Aphasics' discourse errors differed only in degree, not qualitatively, from those of normals. The language of the aphasics' discourses was reduced in both complexity and amount. It was found that the aphasics had difficulties in producing summaries and giving morals for the stories when compared with the normals. Both the content and clarity of the discourses produced by the aphasics were rated lower than those produced by the normals.     

Consolidation of Memory for Odor–Reward Association: β-Adrenergic Receptor Involvement in the Late Phase

Experimentally naive rats can learn rapidly to discriminate among three odors to obtain food reinforcement. After three massed trials, they show almost errorless performance. This task has proved to be useful in studying time-dependent postacquisition intracellular processes necessary for long-term memory. The present experiments evaluated the temporal dynamics of the role of β-noradrenergic receptors in long-term consolidation. Rats were implanted with intracerebroventricular cannulae and trained in a single session to find reinforcement in a hole in a sponge impregnated with a particular odor. Injections of the β-receptor antagonist timolol were made at 5 min, 1, 2, or 5 hr after training. Memory and relearning ability were evaluated 48 hr later. Rats treated with timolol 2 hr after training showed a memory deficit at the retention test, but were able to relearn the task normally. Injections at the earlier or later time points were ineffective. The results reinforce previous observations with systemic injections that β-noradrenergic receptors are involved in the late phase of memory consolidation and suggest a critical time window during which they are necessary. The time window is compatible with the current view that long-term memory depends on late involvement of the cAMP cascade leading to new protein synthesis necessary for synaptic reorganization.
