The development of children's action memory: When do actions speak louder than words?

Summary Although acting consistently has been found to improve memory, the reasons for this are unclear. In this investigation, we tested whether acting improves recall by integrating separate elements within an action into an organized whole and whether this process may be strategic. First graders, fourth graders, and college-aged adults listened to, acted out, or watched the performance of action-object phrases and then verbally reported or enacted the phrases. Phrases composed of transitive verbs were expected to be integrated more by action than phrases composed of intransitive verbs, and consequently recalled better, especially by the younger children. Recall increased between first and fourth grades, suggesting that some aspects of action memory may be strategic; however, there was no evidence that acting improves recall by means of integration. The pattern of results suggested that the nature of an action's outcome may contribute to the enactment effect.     

Seeing “us vs. them”: Minimal group effects on the neural encoding of faces

Faces are inherently social, but the extent to which social group information affects early face processing remains unknown. To address this issue, we examined cortical activity associated with structural encoding of novel ingroup vs. outgroup faces. Participants were assigned to one of two arbitrarily-defined groups using the minimal group procedure, and event-related potentials (ERPs) were recorded while participants categorized faces of people identified as members of their novel ingroup vs. outgroup. Our analysis focused on the N170 component of the ERP, which peaks 170 ms following face onset and reflects face structural encoding. Ingroup faces elicited larger N170 amplitudes than outgroup faces, suggesting that mere group information affects this initial stage of face perception. These findings show that social categories influence how we “see” faces, thus providing insight into the process through which categorizations may lead to biased intergroup perceptions.     

Determination of problems in patients with post‐laryngectomy

The purpose of this study is the determination of the physical and psychosocial problems of total and partial laryngectomies. A total of 25 patients, who were operated with the diagnosis of larynx carcinoma in 2010 at Gazi University Faculty of Medicine Otolaryngology Department, were included in the study. They were evaluated with the help of the Personal Information Form (PIF) and the Determination Form of Post Laryngectomy Problem (DFPLP) for the problems they encountered after the operation. Total laryngectomy (TL) was performed on 76% of patients. It was determined that patients undergoing total laryngectomy experienced some physical and psycho‐social problems such as problems in sleep (31.6%), smell (52.6%), taste (36.8%), and difficulty in swallowing solid foods (36.8%). Furthermore in patients with TL surgery whilst 47.4% of them think that their sexual lives were affected rather negatively, this rate was determined as 33.3% in patients with partial laryngectomy surgery (PL). The psychosocial score averages of the patients who had smell and taste disorders were significantly lower (p < 0.05). The patients, who underwent a laryngectomy operation, experienced many physical, social, and psychological problems. Thus, medical personnel also need to pay attention to these concomitant problems that occur during the treatment of the primary disease and the application of necessary supplementary treatments such as voice prosthesis, pre‐op and post‐op counseling, and anti‐depressants seems significant in terms of increasing the life quality of the patients.     

Anticipation and Source-Monitoring Errors: Children's Memory for Collaborative Activities

When asked to remember who contributed what to the completion of shared, goal-directed activities, children exhibit a bias to over-attribute contributions to themselves, recoding partners' actions as their own. The goals of the 3 experiments reported here were to explore task characteristics that might influence these recoding processes, and as a result, reveal more about them. The timing of the child's contributions in relation to the partner's actions was found to be crucial for recoding (Experiments 1 and 3). The availability of a model outcome affects recoding as well (Experiment 2), but appears not to be a prerequisite. In the absence of a physical outcome, recoding is still observed (Experiment 3). Anticipation of the partner's actions appears to account for all of these effects. Findings have implications for understanding children's source monitoring abilities as well as for understanding internalization processes thought to support collaborative learning.

Linguistic analysis of a bilingual stutterer

The ultimate test of the adequacy of linguistic models of fluency breakdown is the degree to which they may account for patterns of dysfluency in the speech of a stutterer who is fluent in more than one language. We present the case of an adult bilingual stutterer (Spanish-English), whose spontaneous language in both Spanish and English was structurally analyzed to assess the relationships of phonological and syntactic structure to the frequency and location of fluency breakdown. Our findings suggest that syntax is probably a greater determinant of stuttered moments than is phonology. Additionally, similarities and differences between English and Spanish sentence structure were associated with similarities and differences in the loci of dysfluencies across the two languages. The need for crosslinguistic research utilizing monolingual and bilingual speakers of languages other than English is emphasized.
