Parentification and Resilience Among Students With Clinical and Nonclinical Aspirations: A Cross‐Sectional Quantitative Study

This study examined the relationship between level of parentification and resilience among students with clinical and nonclinical aspirations in Malaysia. A total of 419 college students were surveyed using the Parentification Questionnaire (Jurkovic & Thirkield, 1998 ) and Connor–Davidson Resilience Scale (Connor & Davidson, 2003 ). Results showed that clinical students were significantly higher in parentification compared with nonclinical students, and parentification positively predicted resilience. Implications for multicultural counseling and research were discussed.

Extreme malleability of preferences: Absolute preference sign changes under uncertainty

Malleability of preferences is a central tenet of behavioral decision theory. How malleable preferences really are, however, is a topic of debate. Do preference reversals imply preference construction? We argue that to claim preferences are construed, a demonstration of more extreme preference malleability than simple preference reversals is required: absolute preference sign changes within participants. If respondents value a prospect positively in 1 condition but negatively in a different condition, preferences cannot be considered stable. Such absolute preference sign changes are possible under uncertainty. In 2 incentive‐compatible experiments, we found participants were willing to pay to take part in a gamble and also demanded to be compensated to take part in a subsequent gamble with identical outcomes and probabilities. Such absolute preference sign changes within participants led to simultaneous risk aversion and risk seeking for the same risky prospect, suggesting that, at least in the domain of risky decisions, consumers' preferences are indeed malleable and construed.     

Awareness training reduces college students' speech disfluencies in public speaking

Recent research suggests that a modified habit reversal procedure, including awareness training alone or combined with competing response training, is effective in decreasing speech disfluencies for college students. However, these procedures are potentially lengthy, sometimes require additional booster sessions, and could result in covariation of untargeted speaker behavior. We extended prior investigations by evaluating awareness training as a sole intervention while also measuring collateral effects of treatment on untargeted filler words and rate of speech. We found awareness training was effective for all participants without the use of booster sessions, and covariation between targeted filler words and secondary dependent variables was idiosyncratic across participants.     

Equivalence classification by California sea lions using class-specific reinforcers

The ability to group dissimilar stimuli into categories on the basis of common stimulus relations (stimulus equivalence) or common functional relations (functional equivalence) has been convincingly demonstrated in verbally competent subjects. However, there are investigations with verbally limited humans and with nonhuman animals that suggest that the formation and use of classification schemes based on equivalence does not depend on linguistic skills. The present investigation documented the ability of two California sea lions to classify stimuli into functional classes using a simple discrimination reversal procedure. Following the formation of functional classes in this context, the second experiment showed transfer of the relations that emerged between class members to a matching-to-sample procedure. The third experiment demonstrated that the functional classes could be expanded through traditionally defined equivalence relations. In these three experiments, appropriate within-class responding produced class-specific food reinforcers. Experiment 3 addressed the role of these reinforcers in equivalence classification and showed that the class-specific reinforcers were sufficient to relate new stimuli to the functional classes. These findings show that sea lions can form equivalence classes in simple and conditional discrimination procedures, and that class-specific reinforcers can become equivalence class members.     

Breaking the habit: Does fracturing your wrist change your travel and driver behaviour?

When someone breaks their wrist it presents a disruption to everyday routine. Some of this is as a result of having to change travel patterns. This paper investigates the changes people make to their travel behaviour in the light of an unexpected change in their situation caused by fracturing their wrist and wearing a forearm plaster cast. One hundred and eleven participants, approached as they were having their plaster cast removed, completed a questionnaire addressing travel behaviour change, driver safety and information provision covering their time in a plaster cast (typically an average of 5–6 weeks). Eighteen percent of participants drove during the time they had a forearm plaster cast on. All reported they felt safe in doing so and that wearing the plaster cast did not compromise safety, though it was uncomfortable and compensatory behaviours took place. Risk and affective scales did not predict whether participants drove in a cast, suggesting that practical and utilitarian, rather than psychosocial, reasons were the motivation for driving in a plaster cast. Eighty-two percent found other ways of travelling without using their car. Participant’s use of buses and trains, walking and taking lifts were all increased and overall, across all modes of transport, participants travelled fewer miles but made more journeys. There was a reduction in cycling, especially for those who drove in a cast, suggesting cyclists who broke their wrist changed to driving while their arm was in a cast. Information provision did not affect whether someone drove or not. Implications for providing travel information to help people avoid car use while their forearm is in a cast and maintaining behaviour change afterwards are discussed.     

Concurrent nonindependent fixed‐ratio schedules of alcohol self‐administration: Effects of schedule size on choice

Choice behavior was studied under concurrent nonindependent fixed‐ratio fixed‐ratio (nFR) schedules of reinforcement, as these schedules result in frequent changeover responses. With these schedules, responses on either operandum count toward the completion of the ratio requirements of both schedules. Five monkeys were subjects, and two pairs of liquid reinforcers were concurrently available: 16% (w/v) and 0% ethanol or 16% and 8% ethanol. For each pair of reinforcers, the nFR sizes were systematically altered across sessions while keeping the schedule size equal for both liquids. Responding varied as a function of reinforcer pair and nFR size. With the 16% and 0% pair, higher response rates were maintained by 16% and were an inverted U‐shape function of nFR size. With 16% and 8%, a greater number of responses initially occurred on the schedule that delivered 8% ethanol. However, as nFR size increased, preference reversed such that responses that delivered 16% ethanol were greater. When the nFR size was subsequently decreased, preference reverted back to 8%. Number of responses emitted per delivery was a dependent variable and, in behavioral economic terms, was the price paid for each liquid delivery. With 16% and 0%, changeover responses initially increased and then decreased as schedule size became larger. In contrast, with the 16% and 8% pair, changeover responses increased directly with schedule size. Responding under nFR schedules is sensitive to differences in reinforcer magnitude and demonstrates that relative reinforcing effects can change as a function of schedule size.     

Habit reversal as a treatment for chronic skin picking in typically developing adult male siblings.

In this study, habit reversal was evaluated as a treatment for skin picking in typically developing adult male siblings using a nonconcurrent multiple baseline across participants design. Results showed socially valid decreases in reported picking as a result of treatment.     

Evaluating the duration of the competing response in habit reversal: a parametric analysis.

The effectiveness of habit reversal was compared across three different competing response (CR) durations. Results showed that 1‐min and 3‐min CR durations were associated with short‐term and long‐term increases in nail length for people who bit their nails. A 5‐s CR duration produced immediate increases in nail length that were not maintained. Social validity data were consistent with these findings.     

Think globally: cross-linguistic variation in electrophysiological activity during sentence comprehension

This paper demonstrates systematic cross-linguistic differences in the electrophysiological correlates of conflicts between form and meaning (“semantic reversal anomalies”). These engender P600 effects in English and Dutch (e.g. [Kolk et al., 2003] and [Kuperberg et al., 2003]), but a biphasic N400 - late positivity pattern in German (Schlesewsky and Bornkessel-Schlesewsky, 2009), and monophasic N400 effects in Turkish (Experiment 1) and Mandarin Chinese (Experiment 2). Experiment 3 revealed that, in Icelandic, semantic reversal anomalies show the English pattern with verbs requiring a position-based identification of argument roles, but the German pattern with verbs requiring a case-based identification of argument roles. The overall pattern of results reveals two separate dimensions of cross-linguistic variation: (i) the presence vs. absence of an N400, which we attribute to cross-linguistic differences with regard to the sequence-dependence of the form-to-meaning mapping and (ii) the presence vs. absence of a late positivity, which we interpret as an instance of a categorisation-related late P300, and which is observable when the language under consideration allows for a binary well-formedness categorisation of reversal anomalies. We conclude that, rather than reflecting linguistic domains such as syntax and semantics, the late positivity vs. N400 distinction is better understood in terms of the strategies that serve to optimise the form-to-meaning mapping in a given language.
