Action video game experience affects oculomotor performance

Action video games have been show to affect a variety of visual and cognitive processes. There is, however, little evidence of whether playing video games can also affect motor action. To investigate the potential link between experience playing action video games and changes in oculomotor action, we tested habitual action video game players (VGPs) and non-video game players (NVGPs) in a saccadic trajectory deviation task. We demonstrate that spatial curvature of a saccadic trajectory towards or away from distractor is profoundly different between VGPs and NVGPs. In addition, task performance accuracy improved over time only in VGPs. Results are discussed in the context of the competing interplay between stimulus-driven motor programming and top–down inhibition during oculomotor execution.     

Can You Feel It? Negative Emotion,Risk, and Narrative in Health Communication

Eliciting emotional responses to mass media messages can be an effective means of changing public health attitudes, intentions and behaviors. This conceptual paper proposes that emotional responses to such media messages can be message-referent, plot-referent, and/or self-referent. Self-referent emotional responses are expected to have a direct effect in motivating behavior change, particularly as they are likely to be associated with an increase in perceived personal risk. Message-referent and plot-referent emotional responses are proposed to have indirect effects on the individual, primarily by stimulating self-referent emotions, and prompting interpersonal discussion about the message. In this paper, it is argued that narrative is a particularly effective message format with which to elicit self-referent emotional responses.     

Distracted by Details: Narrative Influence Following Conflicting Stories

Work on narrative influence has demonstrated that stories can have a strong effect on people's thoughts and attitudes. However, existing research has not addressed how people respond to multiple stories endorsing different conclusions. The current studies examined how reading two conflicting narratives influences people's decisions about a subsequent situation, with particular emphasis on how resemblances between the narratives and the situation moderate the effects. Across two studies, participants read two testimonials that described the successful use of different treatments for a medical disorder. Participants subsequently made treatment recommendations for a patient who resembled one of the testimonials in treatment-relevant ways. The key manipulation was whether the patient also resembled the other testimonial in treatment-irrelevant ways. Both studies found that these distracting, irrelevant similarities led to less appropriate treatment recommendations. The effect on decision confidence, however, was less clear, with some suggestion of both an increase (Study 1) and a decrease (Study 2) in confidence.     

ENHANCING THE ACCURACY OF LOW‐FREQUENCY BEHAVIOR DATA COLLECTION BY DIRECT‐CARE STAFF

Accurate data collection on low‐frequency problem behavior is imperative given the paucity of opportunities to observe, record, and assess responding. Infrequently occurring behavior also provides a challenge for staff training relative to data collection. The present study evaluated the use of task clarification and feedback to teach direct‐care staff members to take data on recorded, simulated problem behavior. Results indicated that the procedures were effective in increasing accuracy not only in the contrived scenarios but also for problem behavior in the natural environment. These data suggest that task clarification and feedback on simulated problem behavior may be an effective method to increase accurate data collection on problem behavior in the natural environment.

Understanding the multiframe caricature advantage for recognizing facial composites

Eyewitnesses often construct a “composite” face of a person they saw commit a crime, a picture that police use to identify suspects. We described a technique (Frowd, Bruce, Ross, McIntyre, & Hancock, 2007) based on facial caricature to facilitate recognition of these images: Correct naming substantially improves when composites are seen with progressive positive caricature, where distinctive information is enhanced, and then with progressive negative caricature, the opposite. Over the course of four experiments, the underpinnings of this mechanism were explored. Positive-caricature levels were found to be largely responsible for improving naming of composites, with some benefit from negative-caricature levels. Also, different frame-presentation orders (forward, reverse, random, repeated) facilitated equivalent naming benefit relative to static composites. Overall, the data indicate that composites are usually constructed as negative caricatures.     

The role of attention in subitizing: Is the magical number 1?

Subitizing, the fast and accurate enumeration of up to about 3 or 4 objects, has often been thought to be dependent on limited-capacity preattentive mechanisms. We used an attentional blink paradigm to investigate the extent to which subitizing requires attentional resources. On each trial, subjects identified a target letter in an RSVP stream and then enumerated dots presented in the stream that were either simultaneous with the target letter or followed it by up to 400 ms. For numerosities from 2 to 9, evidence of an attentional blink was observed; only enumeration of 0 or 1 elements was independent of lag. Thus, even enumeration of 2–3 objects, which is within the traditional subitizing range, appears to require attentional resources. The relation of this work to studies on the attentional requirements of detecting a unique item among distractors, a supposedly preattentive discrimination, is briefly discussed.     

Attention switching between global and local elements: Distractor category and the level repetition effect

When selecting information at global and local levels of hierarchical stimuli, there is a robust effect of level repetition in which performance is more efficient when a target is presented at the same level as the previous target. Moreover, the effect is symmetrical; it affects global and local processing equally. Evidence exists to suggest the effect may be automatic; however, we show here that the level repetition effect requires some amount of competition from the ignored level, and that the nature of the irrelevant information can determine whether the level-repetition effect is symmetrical (global and local responses are affected equally) or asymmetrical (global responses are more greatly affected than local responses). In Experiment 1, the level-repetition effect was eliminated when information at the distracting level was invariant across trials; effects of hemisphere bias and level repetition were observed only when suppression or filtering of distractor information was required. Experiment 2 demonstrated that simple featural variance is sufficient to produce the level repetition effect and that the symmetry of the level-repetition effect is sensitive to Garner-type interference that affects global processing to a greater extent than local processing. In Experiment 3, we showed that the absence of a level-repetition effect in the invariant distractor condition persists when the position of relevant stimuli is random within a block, a manipulation which should greatly reduce the contribution of controlled attention. We conclude that simple featural variance at the ignored level is critical to produce the advantage of level repetition, and that the size of the effect can be asymmetrical.     

Effects of Data Noise on Statistical Judgement

People made forecasts from graphically presented time series. Series were sinusoids overlaid by a zero or positive linear trend and a zero, low, moderate, or high level of noise. Forecasting performance was affected by both these variables. However, it did not correlate with ability to identify the trend and correlated significantly with ability to detect the sinusoidal pattern only when series were noise-free. A second experiment showed that the effect of data noise was not influenced by the number of forecasts that people made from a series. These findings are consistent with the view that data noise does not affect the way that forecasts are made but that it impairs them for two reasons. First, it renders the anchor-and-adjust heuristics underlying them less effective. Second, it causes people to add more noise to their judgements in their attempts to make them representative of the data.     

Essener Evaluation der Unterbringung in der Entziehungsanstalt

Over the past 20 years various studies have yielded findings regarding the treatment of offenders in forensic addiction treatment centers in Germany (section 64 of the Penal Code). For a number of reasons these studies hardly allow quantification of the assessment of the rehabilitative success of treatment. In 2009 the Institute of Forensic Psychiatry at the University of Essen, Germany was commissioned to engage in a long-term evaluation study that will be completed in 2017. The project is supported by the Ministry of Health of the State of North-Rhine Westphalia. The present paper summarizes the methodology of the study and draws up an interim balance of the data collection. The study involves the follow-up of 300 patients from 16 forensic mental hospitals from entry into the institution to discharge and further on to living in the community including a“time at risk of at least 2 years. A number of these patients will drop out of treatment by being sent back to prison. The rate of criminal recidivism in the complete group of subjects will be compared to a matched control group of 300 offenders serving a prison sentence only. Potential error sources related to the data collection are discussed in the paper.
