Impact of interpersonal problem-solving training on preschoolers' social competency

In order to test Shure and Spivack's theoretical position that a child's ability to verbally generate solutions to interpersonal problems and think about their consequences is directly related to the child's behavioral adjustment, preschoolers were tested on verbal problem-solving skills and their classroom behavior was rated by their teachers. Further, their behavior was observed by independent observers. No significant relationship between problem-solving skills and behavior was found. Following assessment, 54 of these children completed an 11-week training program, designed by Shure and Spivack, to improve their ability to think through and verbally generate solutions to interpersonal problems and to examine the possibility of mediation of such training to behavioral improvement. Preschoolers' ability to verbally generate alternative solutions to problems significantly increased due to training, however, this increase did not have an ameliorative effect on behavioral adjustment.     

Inferences,affects, and intentions in a model of paranoia

Models of psychopathologies can be construed as modifications to the normal purposive behavior of an organism. The particular elements of purposive behavior to be emphasized here are (1) deriving facts about the environment (inferences), (2) attending to the self's needs, desires, and interests (affects), and (3) choosing directions and goals to fulfill these interests (intentions). A series of processes in a model of paranoia which performs these tasks will be described. We also describe the modifications made by the paranoid processes to the normal processes. A computer simulation has been constructed to test the model.     

Acoustic parameters of infant-directed singing in mothers with depressive symptoms

The purpose of this study was to explore the relationship between mothers’ depressive symptoms and the acoustic parameters of infant-directed (ID) singing. Participants included 80 mothers and their 3- to 9-month-old infants. A digital recording was made of each mother's voice while singing to her infant. Extraction and analyses of vocal data revealed a main effect of tempo, meaning that as mothers reported more depressive symptoms, they tended to sing faster to their infants. Additionally, an interaction effect indicated that mothers with depressive symptoms were more likely to sing with tonal key clarity to their male infants. These findings suggest that as mothers experience depressive symptoms, their ID singing may lack the sensitivity and emotional expression that infants need for affect regulation. An intervention that combines interaction coaching and ID singing may help mothers with depressive symptoms to engage in sensitive and emotionally synchronized interactions with their infants.     

Trans-saccadic perception

A basic question in cognition is how visual information obtained in separate glances can produce a stable, continuous percept. Previous explanations have included theories such as integration in a trans-saccadic buffer or storage in visual memory, or even that perception begins anew with each fixation. Converging evidence from primate neurophysiology, human psychophysics and neuroimaging indicate an additional explanation: the intention to make a saccadic eye movement leads to a fundamental alteration in visual processing itself before and after the saccadic eye movement. We outline five principles of 'trans-saccadic perception' that could help to explain how it is possible - despite discrete sensory input and limited memory - that conscious perception across saccades seems smooth and predictable.
