Covert shifts of attention precede involuntary eye movements

There is considerable evidence that covert visual attention precedes voluntary eye movements to an intended location. What happens to covert attention when an involuntary saccadic eye movement is made? In agreement with other researchers, we found that attention and voluntary eye movements are tightly coupled in such a way that attention always shifts to the intended location before the eyes begin to move. However, we found that when an involuntary eye movement is made, attention first precedes the eyes to the unintended location and then switches to the intended location, with the eyes following this pattern a short time later. These results support the notion that attention and saccade programming are tightly coupled.     

An evaluation of in vivo desensitization and video modeling to increase compliance with dental procedures in persons with mental retardation

Fear of dental procedures deters many individuals with mental retardation from accepting dental treatment. This study was conducted to assess the effectiveness of two procedures, in vivo desensitization and video modeling, for increasing compliance with dental procedures in participants with severe or profound mental retardation. Desensitization increased compliance for all 5 participants, whereas video modeling increased compliance for only 1 of 3 participants.     

A day of great illumination: B. F. Skinner's discovery of shaping

Despite the seminal studies of response differentiation by the method of successive approximation detailed in chapter 8 of The Behavior of Organisms (1938), B. F. Skinner never actually shaped an operant response by hand until a memorable incident of startling serendipity on the top floor of a flour mill in Minneapolis in 1943. That occasion appears to have been a genuine eureka experience for Skinner, causing him to appreciate as never before the significance of reinforcement mediated by biological connections with the animate social environment, as opposed to purely mechanical connections with the inanimate physical environment. This insight stimulated him to coin a new term (shaping), and also led directly to a shift in his perspective on verbal behavior from an emphasis on antecedents and molecular topographical details to an emphasis on consequences and more molar, functional properties in which the social dyad inherent to the shaping process became the definitive property of verbal behavior. Moreover, the insight seems to have emboldened Skinner to explore the greater implications of his behaviorism for human behavior writ large, an enterprise that characterized the bulk of his post-World War II scholarship.     

Unintended consequences: ventures and misadventures in the education of professional psychologists

Increasing professionalization of psychology, accelerated by expansion of professional schools, has evoked concern among critics, who claim that many practitioners ignore scientific research and engage in practices that are demonstrably useless or harmful. Recent data on admissions to professional schools and performance of professional school graduates show cause for concerns of the critics. If psychology is to maintain its stature as a profession, exclusionary controls as well as hortatory requirements for the practice of psychology and the education of practitioners must be established and enforced. Before more stringent standards can be imposed, convincing means for evaluating competence in professional work and quality in professional education must be developed. Local and institutional actions to advance those aims are proposed.     

Like mother,like daughter: similarities in narrative style

Children (2-5-year-olds and 8-13-year-olds) and their parents were independently interviewed about highly salient events: injuries serious enough to necessitate hospital emergency room treatment. Free recall narratives were scored using 14 measures of length, elaborative detail, cohesion, coherence,and provision of context. Mothers' narratives were more cohesive and coherent than fathers', and girls' narratives differed from boys' in parallel ways. Parent and child measures were correlated, and narratives of mother-daughter dyads (for the older daughters) showed striking similarity in all 5 properties, whereas there was no narrative similarity within father-son, mother-son, or father-daughter dyads. This suggests a special status for mother-daughter dyads in terms of how events come to be linguistically represented in narrative.     

Intensity and color of language in attitude change and emotion

This study examined whether messages using or not using emotionally intense language combined with certain colors, i.e., red, white, or blue, to effect attitude change. Emotionally intense messages were more positively associated with attitude change than were those with low emotional intensity, but no interaction effects or main effects for color were found.     

Sources of openness/intellect: cognitive and neuropsychological correlates of the fifth factor of personality

We characterize Openness/Intellect as motivated cognitive flexibility, or cognitive exploration, and develop a neuropsychological model relating it to dopaminergic function and to the functions of the prefrontal cortex (PFC). Evidence is reviewed for sources of Openness/Intellect shared with Extraversion and sources unique to Openness/Intellect. The hypothesis that the cognitive functions of the dorsolateral PFC are among the latter was tested using standard measures of cognitive ability and a battery of tasks associated with dorsolateral PFC function (N=175). Dorsolateral PFC function, as well as both fluid and crystallized cognitive ability, was positively related to Openness/Intellect but no other personality trait. Additionally, facet level analysis supported the characterization of Openness/Intellect as a primarily cognitive trait.     

The edge complex: implicit memory for figure assignment in shape perception

Viewing a stepped edge is likely to prompt the perceptual assignment of one side of the edge as figure. This study demonstrates that even a single brief glance at a novel edge gives rise to an implicit memory regarding which side was seen as figure; this edge complex enters into the figure assignment process the next time the edge is encountered, both speeding same-different judgments when the figural side is repeated and slowing these judgments when the new figural side is identical to the former ground side (Experiments 1A and 1B). These results were obtained even when the facing direction of the repeated edge was mirror reversed (Experiment 2). This study shows that implicit measures can reveal the effects of past experience on figure assignment, following a single prior exposure to a novel shape, and supports a competitive model of figure assignment in which past experience serves as one of many figural cues.
