Subliminal priming of winning images prompts increased betting in slot machine play

In 2 experiments (n = 327), participants played a computerized slot machine game. Some participants had the jackpot symbols repeatedly flashed for 30 ms during preliminary play. Exposure to the subliminal jackpot prime led to more betting and confidence on a final spin. In Experiment 2, this effect only occurred for those who placed their bets immediately following exposure to the primes. Betting and confidence returned to baseline levels if participants were forced to wait for 5 minutes before betting. This finding supports a category priming explanation rather than a goal activation explanation for the effect. Results are discussed in the context of research on subliminal priming, and as an example of an application of subliminal priming effects to consumer psychology.     

Neuropsychological Functioning in Early Hydrocephalus: Review From a Developmental Perspective

Children with hydrocephalus have deficits in several neuropsychological domains. The most notable are motor, visuoperceptual, and visuomotor function. These deficits are multiply determined and depend on the etiology and severity of the hydrocephalus to a large extent. Corpus callosum abnormalities resulting from stretching of callosal fibers and other cortical white matter tracts are implicated as contributory to these deficits. Enlarged ventricles and associated compression of posterior cortical areas also correlate with cognitive impairment. Distinguishing which cognitive domain negatively impacts on the child’s functioning and which domains influence behavior in isolation or in combination has been the subject of numerous studies. Developmentally, we know little about the emergence of neuropsychological functioning in children with hydrocephalus. Study of the effects of hydrocephalus at different stages of development is useful to clinicians and researchers interested in the impact of diffuse neurophysiological damage on cognition in the developing brain. The medical and neuropsychological literature have begun to inform about these effects. The core deficits in hydrocephalus have yet to be explicated and a focus on investigations that answer these questions is required. This review summarizes the current knowledge about neurocognitive sequelae of hydrocephalus.     

Response retrieval in a go/no-go priming-of-popout task

Priming of popout is the finding that singleton search is faster when features of a target and of nontargets are repeated across trials than when the features switch. Theoretical accounts suggest that intertrial repetition influences perceptual and attentional selection processes, episodic retrieval processes, or both. The present study combined a popout search task with a go/no-go task. In Experiment 1, the nontarget distractors in each display carried the go/no-go feature, and in Experiment 2, the texture of all items carried the go/no-go feature. Results showed that the go/no-go task moderated the intertrial repetition effects. In Experiment 1, the target color elicited retrieval of the preceding distractor color and associated no-go response, resulting in larger interference effects. In Experiment 2, the target color elicited retrieval of the preceding target color and no-go response, resulting in reduced facilitation effects. Additional results from both experiments showed that the colors in a search display also influenced target selection on the following trial. Taken together, the results of both experiments suggest that intertrial repetition influences both early selection and postselection retrieval processes.     

Integrating visual images and visual percepts across time and space

Recent studies suggest that visual information can be integrated over a relatively long delay (> 1500 ms) to form a more complete representation (image-percept integration). The current studies investigated whether this process can occur between stimuli that differ in their spatial properties. Participants viewed two dot arrays that filled all but one space in a square or rectangular grid when combined, and reported the missing space. The arrays differed either in size or orientation. Performance reached a comparable level as when spatial properties were matched. However, such performance depends on at least two processes. We suggest an early encoding process and a later image formation/spatial attention reallocation process are required. The flexibility of the image-percept integration process suggests a strong mechanism to form more complete or detailed representations over time, even when the retinal size and orientation of the scene may change between successive views.     

Exercise environment,self-efficacy,and affective responses to acute exercise in older adults

Abstract

Increasing evidence suggests that regular physical activity can have considerable psychological, as well as physical, benefits in the elderly. Although factors such as exercise dosage may be implicated in exercise-induced affect responses, it has also been suggested that social and psychological factors might influence this relationship. This study examined the roles played by exercise environment (group versus alone) and self-efficacy in affective change in 80 older adults (M age = 66 yrs) over the course of three acute exercise bouts. Using latent growth curve methodology and statistically controlling for duration and intensity of exercise, we were able to demonstrate that social (group) environments resulted in statistically significant improvements in feeling state responses when contrasted with a condition in which the participants exercised alone. In addition, increases in self-efficacy were associated with more positive and less negative feeling states. Environmental factors that might influence the exercise-affect response are discussed and recommendations for subsequent exercise, efficacy, affect research made.     

Dante’s Divine Comedy and modern depth therapy

The author discusses a connection between the modern analysand’s experience of depth therapy and the Christian pilgrim’s experience of confession, penitence and transformation as described by Dante in his Divine Comedy. She looks at structure and order in the context of psychotherapy. Taking Adriana Mazzarella’s ‘In Search of Beatrice’ as a guide, she examines a Jungian interpretation of the poem as an analogy of therapeutic initiation. She explores the idea of cultural complexes via the study of the medieval world view as one distinct from our own. She demonstrates the way in which study of the Comedy unexpectedly helped her survive an experience of long-term psychotherapeutic work.     

Finding Where and Saying Where: Developmental Relationships Between Place Learning and Language in the First Year

The relationship between emergent spatial understanding in different cognitive domains, including navigation and language, has rarely been studied using methods that allow for the examination of individual differences. In this study the authors explored emergent place learning and its relationship to early spatial language, namely prepositions, in 16- to 24-month-old children. Children were tested using a spatial task adapted from the Morris water maze, and the MacArthur Communicative Development Inventory. In the place-learning task, children were placed in a circular enclosure and a puzzle was hidden under the floor at one location. Before each trial, children were disoriented and placed in the maze at a different starting position. Their search types and success at finding the puzzle were coded. As expected, older children demonstrated more spatial searches and better place-learning skills (finding the goal), as well as greater overall expressive vocabulary. Place learning and language did not correlate with each other once age was partialled, with one crucial exception: a theoretically predicted correlation between prepositions and goal localization.     

Gender Bias on the Thematic Apperception Test

Thirty male and 30 female college students generated stories to a set of nine Thematic Apperception Test (TAT) cards with either male or female stimulus characters. The Fine scoring system was factor analyzed to produce seven factor clusters plus three outcome variables. Multiple analysis of variance (MANOVA) revealed a main effect for type of card. The female TAT cards elicited significantly more responses on the General Concerns scale than did the male TAT cards. A main effect for subject gender showed the females gave more responses than males on the Interpersonal Relations scale. No differences were found on the outcome variables.     

Contextual Cueing Effects Across the Lifespan

The authors evaluated age-related variations in contextual cueing, which reflects the extent to which visuospatial regularities can facilitate search for a target. Previous research produced inconsistent results regarding contextual cueing effects in young children and in older adults, and no study has investigated the phenomenon across the life span. Three groups (6, 20, and 70 years old) were compared. Participants located a designated target stimulus embedded in a context of distractor stimuli. During exposure, the location of the target could be predicted from the location of the distracters in each display. During test, these predictable displays were intermixed with new displays that did not predict the target location. Response times to locating predictable relative to unpredictable targets were compared. All groups exhibited facilitation effects greater than 0 (95% CIs [.02, .11], d = .4; [.01, .12], d = .4; and [.01, .10], d = .4, for the children, young adults, and older adults, respectively) indicating that contextual cueing is robust across a wide age range. The relative magnitude of contextual cueing effects was essentially identical across the age range tested, F(2, 103) = 1.71, ηρ² = .02. The authors argue that a mechanism that uses environmental covariation is available to all age ranges, but the expression of the contextual cueing may depend on the way it is measured.
