Upper-left gaze bias reveals competing search strategies in a reverse Stroop task

Three experiments with a total of 87 human observers revealed an upper-left spatial bias in the initial movement of gaze during visual search. The bias was present whether or not the explicit control of gaze was required for the task. This bias may be part of a search strategy that competed with the fixed-gaze parallel search strategy hypothesized by Durgin [Durgin, F. H. (2003). Translation and competition among internal representations in a reverse Stroop effect. Perception &Psychophysics, 65, 367-378.] for this task. When the spatial probabilities of the search target were manipulated either in accord with or in opposition to the existing upper-left bias, two orthogonal factors of interference in the latency data were differentially affected. The two factors corresponded to two different forms of representation and search. Target probabilities consistent with the gaze bias encouraged opportunistic serial search (including gaze shifts), while symmetrically opposing target probabilities produced latency patterns more consistent with parallel search based on a sensory code.

Buffering negative effects of immigration on cognitive,social, and educational development: A multinational meta-analysis of child and adolescent prevention programmes

Growing up in migrant families is a well-known distal risk factor related to poorer outcomes in child and adolescent health, academic, socioemotional and behavioural development. This article reviews the effects of various prevention measures such as early education programmes, cognitive and language training or parent and teacher training on child and adolescent developmental outcomes in immigration samples. Using several comprehensive literature searches, we found 138 research reports with 141 studies and 175 comparisons on preventing negative effects of immigration. Overall, programmes yielded an effect size of d = 0.26 at post-test using the random effect model. These effects decreased over time while still differing significantly from zero. A cross-tabulation of prevention approach/programme type by different outcome domains revealed several important results such as high effects of child cognitive and language training programmes on child academic and language outcomes and relatively low effects of all programmes on child socioemotional outcomes. In addition, individualised and culturally tailored programmes seems to be more effective. However, generalised effects on more distal educational outcomes (e.g., school degrees) were generally weak. Hence, it remains questionable whether individual psychosocial and educational programmes are able to counterbalance the multifaceted risks of immigration.     

Effects of phonological similarity on priming in auditory lexical decision

Two auditory lexical decision experiments were conducted to determine whether facilitation can be obtained when a prime and a target share word-initial phonological information. Subjects responded “word” or “nonword” to monosyllabic words and nonwords controlled for frequency. Each target was preceded by the presentation of either a word or nonword prime that was identical to the target or shared three, two, or one phonemes from the beginning. The results showed that lexical decision times decreased when the prime and target were identical for both word and nonword targets. However, no facilitation was observed when the prime and target shared three, two, or one initial phonemes, These results were found when the interstimulus interval between the prime and target was 500 msec or 50 msec. In a second experiment, no differences were found between primes and targets that shared three, one, or zero phonemes, although facilitation was observed for identical prime-target pairs. The results are compared to recent findings obtained using a perceptual identification paradigm. Taken together, the findings suggest several important differences in the way lexical decision and perceptual identification tasks tap into the information-processing system during auditory word recognition.     

Information selection and use in hypothesis testing: What is a good question,and what is a good answer?

The process of hypothesis testing entails both information selection (asking questions) and information use (drawing inferences from the answers to those questions). We demonstrate that although subjects may be sensitive to diagnosticity in choosing which questions to ask, they are insufficiently sensitive to the fact that different answers to the same question can have very different diagnosticities. This can lead subjects to overestimate or underestimate the information in the answers they receive. This phenomenon is demonstrated in two experiments using different kinds of inferences (category membership of individuals and composition of sampled populations). In combination with certain information-gathering tendencies, demonstrated in a third experiment, insensitivity to answer diagnosticity can contribute to a tendency toward preservation of the initial hypothesis. Results such as these illustrate the importance of viewing hypothesis-testing behavior as an interactive, multistage process that includes selecting questions, interpreting data, and drawing inferences.     

Accounting for HIV Risk Among Men on Methadone

This study explores accounts and reasons for engaging in HIV risk-taking behaviors reported by heterosexual men in methadone treatment programs in the Harlem section of New York City. A convenience sample of 62 men who reported having abused their female partners in the past 12 months participated in 10 focus groups. Data analysis revealed four types of HIV risky accounts, which we labeled nihilistic, hedonistic, fatalistic, and normative. The accounts were rarely found in isolation, but were delivered in rich “performative” constellations. We conclude that normative accounts in particular have important implications for HIV prevention. They show that the (hetero)sexual act is interactive “hard work” to say the least, and condoms have no role interrupting it. In the end, the risks of losing masculine face before a female partner are very much prioritized over long-run HIV risks.     

Measuring individual differences in statistical learning: Current pitfalls and possible solutions

Most research in statistical learning (SL) has focused on the mean success rates of participants in detecting statistical contingencies at a group level. In recent years, however, researchers have shown increased interest in individual abilities in SL, either to predict other cognitive capacities or as a tool for understanding the mechanism underlying SL. Most if not all of this research enterprise has employed SL tasks that were originally designed for group-level studies. We argue that from an individual difference perspective, such tasks are psychometrically weak, and sometimes even flawed. In particular, the existing SL tasks have three major shortcomings: (1) the number of trials in the test phase is often too small (or, there is extensive repetition of the same targets throughout the test); (2) a large proportion of the sample performs at chance level, so that most of the data points reflect noise; and (3) the test items following familiarization are all of the same type and an identical level of difficulty. These factors lead to high measurement error, inevitably resulting in low reliability, and thereby doubtful validity. Here we present a novel method specifically designed for the measurement of individual differences in visual SL. The novel task we offer displays substantially superior psychometric properties. We report data regarding the reliability of the task and discuss the importance of the implementation of such tasks in future research.     

When children ask, "What is it?" what do they want to know about artifacts?

When children ask, "What is it?" are they seeking information about what something is called or what kind of thing it is? To find out, we gave 2-, 3-, and 4-year-olds (32 at each age) the opportunity to inquire about unfamiliar artifacts. An ambiguous question was answered with a name or with functional information, depending on the group to which the children were assigned. Children were inclined to follow up with additional questions about the object when they had been told its name, but seemed satisfied with the answer when they had been told the object's function. Moreover, children in the name condition tended to substitute questions about function for ambiguous questions over the course of the session. These results indicate that children are motivated to discover what kinds of things novel artifacts are, and that young children, like adults, conceive of artifact kinds in terms of their functions.     

Evaluation of a Spiritually Based Child Maltreatment Prevention Training Program

The authors empirically evaluated a spiritually based 1‐day child maltreatment training program. Pretest, posttest, and follow‐up results indicated that participants' recognition of hypothetical maltreatment did not increase after training. Furthermore, although participants decreased their use of items known to dissuade decisions to report, they were less likely to report maltreatment posttraining and 1 month later. Focus group data revealed that participants felt more knowledgeable but insufficiently prepared to respond to maltreatment and that they needed opportunities to practice what they had learned. Suggestions for clergy, pastoral counselors, and mental health professionals working within spiritual communities are provided to inform curriculum advancements.     

Ecstasy Use,Outcome Expectancies,and Sexual Risk Taking

Ecstasy has become one of the most widely used illicit drugs in Australia. This study investigated outcome expectancies as possible motivating and maintaining factors in ecstasy use and sexual risk‐taking behaviour. A sample of regular ecstasy users (N = 220) from Sydney and Canberra, Australia, was recruited for structured face‐to‐face interviews. They also completed an Ecstasy Expectancy Questionnaire. Seven of eight subscales significantly differentiated regular users from non‐users. Interestingly, light and heavier users held similar outcome expectancies, except that light users endorsed items on the sexual enhancement subscale more strongly than heavier users. Further investigation showed that the level of sexual risk taking observed in this sample was high, with the majority of participants reporting multiple partners, “casual” sexual encounters, sex under the influence of substances, and inconsistent condom use. Using logistic regression analyses, a key finding was that positive sex‐related ecstasy outcome expectancies were associated with involvement in disinhibited sexual behaviour under the influence of ecstasy. These effects persisted after statistically controlling for the frequency of ecstasy use. The findings suggest that sexual risk taking is related not only to the disinhibiting properties of ecstasy but also to beliefs that users hold about the effects of the drug.
