Adolescents’ inhibitory control: keep it cool or lose control

Inhibitory control (i.e., the ability to resist automatisms, temptations, distractions, or interference and to adapt to conflicting situations) is a determinant of cognitive and socio‐emotional development. In light of the discrepancies of previous findings on the development of inhibitory control in affectively charged contexts, two important issues need to be addressed. We need to determine (a) whether cool inhibitory control (in affectively neutral contexts) and hot inhibitory control (in affectively charged contexts) follow the same developmental pattern and (b) the degree of specificity of these two types of inhibitory control at different ages. Thus, in the present study, we investigated the developmental patterns of cool and hot inhibitory control and the degree of specificity of these abilities in children, adolescents and adults. Typically developing children, adolescents, and adults performed two Stroop‐like tasks: an affectively neutral one (Cool Stroop task) and an affectively charged one (Hot Stroop task). In the Cool Stroop task, the participants were asked to identify the ink color of the words independent of color that the words named; in the Hot Stroop task, the participants were asked to identify the emotional expression of a face independent of the emotion named by a simultaneously displayed written word. We found that cool inhibitory control abilities develop linearly with age, whereas hot inhibitory control abilities follow a quadratic developmental pattern, with adolescents displaying worse hot inhibitory control abilities than children and adults. In addition, cool and hot inhibitory control abilities were correlated in children but not in adolescents and adults. The present study suggests (a) that cool and hot inhibitory control abilities develop differently from childhood to adulthood – i.e., that cool inhibition follows a linear developmental pattern and hot inhibition follows an adolescent‐specific pattern – and (b) that they become progressively more domain‐specific with age.     

One Frog, Two Frog, Red Frog, Blue Frog: Factors Affecting Children's Syntactic Choices in Production and Comprehension

Two experiments are reported which examine children's ability to use referential context when making syntactic choices in language production and comprehension. In a recent on-line study of auditory comprehension, Trueswell, Sekerina, Hill, and Logrip (1999) examined children's and adults' abilities to resolve temporary syntactic ambiguities involving prepositional phrases (e.g., “Put the frog on the napkin into ¨”). Although adults and older children used the referential context to guide their initial analysis (pursuing a destination interpretation in a one-frog context and a modifier interpretation in a two-frog context), 4 to 5-year olds' initial and ultimate analysis was one of destination, regardless of context. The present studies examined whether these differences were attributable to the comprehension process itself or to other sources, such as possible differences in how children perceive the scene and referential situation. In both experiments, children were given a language generation task designed to elicit and test children's ability to refer to a member of a set through restrictive modification. This task was immediately followed by the “put” comprehension task. The findings showed that, in response to a question about a member of a set (e.g., “Which frog went to Mrs. Squid's house?”), 4- to 5-year-olds frequently produced a definite NP with a restrictive prepositional modifier (e.g., “The one on the napkin”). These same children, however, continued to misanalyze put instructions, showing a strong avoidance of restrictive modification during comprehension. Experiment 2 showed that an increase in the salience of the platforms that distinguished the two referents increased overall performance, but still showed the strong asymmetry between production and comprehension. Eye movements were also recorded in Experiment 2, revealing on-line parsing patterns similar to Trueswell et al.: an initial preference for a destination analysis and a failure to revise early referential commitments. These experiments indicate that child–adult differences in parsing preferences arise, in part, from developmental changes in the comprehension process itself and not from a general insensitivity to referential properties of the scene. The findings are consistent with a probabilistic model for uncovering the structure of the input during comprehension, in which more reliable linguistic and discourse-related cues are learned first, followed by a gradually developing ability to take into account other more uncertain (or more difficult to learn) cues to structure.     

The desire to lose one's identity

The desire to merge identities with an intimate partner was found to be negatively related to psychoticism but related to other social desires, such as the desire for physical closeness and identifying with the achievements of others.     

Aging and maintaining intentions over delays: do it or lose it

When execution of retrieved intentions must be briefly delayed, older adults display deficits in performing those intentions (G. O. Einstein, M. A. McDaniel, M. Manzi, B. Cochran, & M. Baker, 2000). This initial finding was extended by showing age-related deficits with 5-s unfilled delays, with instructions to rehearse during the delay, and with divided attention during initial retrieval of the intention. Performance increased with a break at the end of the delay period, such that when combined with full attention (during retrieval), older adults' performance approached that of younger adults. These results suggest that age compromises maintenance of information in awareness. Consequently, when forced to delay execution of retrieved intentions, older adults may rely more on plan reformulation and subsequent retrieval of the intention from long-term memory at the end of the delay.     

Body image and strategies to lose weight and increase muscle among boys and girls.

This study examined factors that influence body image and strategies to either lose weight or increase muscle among children. Participants were 237 boys and 270 girls. Body mass index (BMI), body dissatisfaction, cognitions and behaviors to both lose weight and increase muscles, as well as self-esteem and positive and negative affect, were evaluated. Self-esteem was associated with body satisfaction, positive affect predicted strategies to lose weight and increase muscles, and negative affect predicted body dissatisfaction and cognitions to lose weight and increase muscles. Boys were more likely to focus on changing muscles. Respondents with higher BMIs were more focused on losing weight butnot muscle. The discussion focuses on health risk behaviors related to eating and exercise among children.     

Temporal discounting in "gain now-lose later" and "lose now-gain later" conditions

Studies on temporal discounting typically involve choosing between two outcomes of the same sign, i.e., positive or negative. For example, participants often are given a choice between a smaller, sooner gain and a larger, but later gain, or (less commonly) the options may be a sooner, larger loss and a later, but smaller loss. In contrast, participants in this study (N= 129; 66 women and 63 men, volunteers from Warsaw, Poland, all employed, with college education, ranging in age from 23 to 50 years, M=32.3 yr., SD=7.4) had to make a yes-or-no decision as to whether they would accept a financial offer involving a combination of a gain and a loss. This offer could be either an immediate gain to be followed later by a larger loss or an immediate loss followed later by a larger gain. Despite the substantial differences between the options in the present study and those in typical discounting studies, the same hyperboloid discounting function that describes choice between immediate and delayed gains also accurately described choice in the substantially different situations presented in the present study. In addition, steeper discounting was observed with a smaller delayed outcome than with a larger delayed outcome.     

Use of diet pills and amphetamines to lose weight among smoking and nonsmoking high school seniors

Used data on 3,305 high school seniors collected as part of the 1984 Monitoring the Future project to examine the relationships among cigarette use, diet pill use, and use of amphetamines for weight loss. Results indicate that females were more likely than males to report use of all three substances. In addition, Whites were more likely than Blacks to use all three substances. Both female and male smokers were more likely than nonsmokers to use diet pills. Amphetamine use for weight loss was positively related to smoking among females, but not among males. The relationships between smoking and diet pill use, and smoking and amphetamine use to lose weight, were maintained when race, sex, and other drug use were controlled simultaneously. Two explanations for these relationships are considered. The first is that smoking is related to the use of most other licit and illicit drugs. The second explanation is that there is a greater preoccupation with weight among smokers, with weight concerns potentially motivating the initiation of smoking.     

Use it or lose it: examining preschoolers' difficulty in maintaining and executing a goal

Individuals with low working memory capacity (e.g. preschoolers) are more prone to goal neglect, or a failure to execute a goal even though it is understood. We examined the role of goal neglect in performance on the Dimensional Change Card Sort by including 'redundant' cards that could be sorted without attending to the rules, as well as the traditional 'conflict' cards that encouraged awareness of the rules. In Experiment 1, 4- and 5-year-old children were administered two card sorts that differed on the proportion of redundant cards presented (20% vs. 80%). Children neglected the goal more often when faced with a preponderance of redundant cards, suggesting that consistent attention to the rules leads to goal maintenance. In Experiment 2, results were replicated even when the post-switch rules were repeated on every trial. Implications for the development of working memory are discussed.     

Concepts without intuition lose the game: commentary on Montero and Evans (2011)

In several papers, Hubert Dreyfus has used chess as a paradigmatic example of how experts act intuitively, rarely using deliberation when selecting actions, while individuals that are only competent rely on analytic and deliberative thought. By contrast, Montero and Evans (Phenomenology and the Cognitive Sciences 10:175?C194, 2011) argue that intuitive aspects of chess are actually rational, in the sense that actions can be justified. In this paper, I show that both Dreyfus??s and Montero and Evans??s views are too extreme, and that expertise in chess, and presumably in other domains, depends on a combination of intuitive thinking and deliberative search, both mediated by perceptual processes. There is more to expertise than just rational thought. I further contend that both sides ignore emotions, which are important in acquiring and maintaining expertise. Finally, I argue that experimental data and first-person data, which are sometimes presented as irreconcilable in the phenomenology literature, actually lead to similar conclusions.     

Win some, lose some: Hypermnesia for actions reflects increased item-specific processing

Memory for simple action phrases (e.g., “Break a match”) improves when subjects perform the actions at study. The relative contribution of item-specific and relational processing to this enactment effect has been an issue of considerable debate. It was addressed in the present study by examining hypermnesia in a multiple-test free recall paradigm, -based on the assumptions that itemspecific processing increases the probability of intertest gains and relational processing protects against intertest forgetting (e.g., Burns, 1993; Klein, Loftus, Kihlstrom, & Aseron, 1989). It was found that the enactment condition produced both significantly more gains and more losses than did the nonenactment condition, resulting in a net gain (hypermnesia) for the enactment condition. The results suggest that enactment promotes item-specific processing at the expense of relational processing.     

When words lose their power: Shiatsu as a strategic tool in psychotherapy

A psychotherapist sometimes reaches the edge of his abilities, the point at which he/she realizes that for a certain client, words lose their power. The therapist may try a variety of psychological approaches, but with no effect, until he/she comes to feel that perhaps the patient simply cannot be helped. This article points the possibility that in certain cases, when psychotherapy is not bearing fruit, the psychotherapist can make use of additional tools to break through the barrier to treatment. These tools can include psychodrama, movement or dance therapy, and many other non- verbal techniques. The additional tool discussed here is Shiatsu (Acupressure), whose integration in certain cases was found to bring about the desired breakthrough, ultimately bringing the patient to the point at which talking was meaningful and effective again.     

Intuitions without concepts lose the game: mindedness in the art of chess

To gain insight into human nature philosophers often discuss the inferior performance that results from deficits such as blindsight or amnesia. Less often do they look at superior abilities. A notable exception is Herbert Dreyfus who has developed a theory of expertise according to which expert action generally proceeds automatically and unreflectively. We address one of Dreyfus’s primary examples of expertise: chess. At first glance, chess would seem an obvious counterexample to Dreyfus’s view since, clearly, chess experts are engaged in deep strategic thought. However, Dreyfus’s argument is subtle. He accepts that analysis and deliberation play a role in chess, yet he thinks that all such thought is predicated on intuitive, arational expert perception, and action. We argue that even the so-called “intuitive” aspect of chess is rational through and through.     

How current feedback and chronic effectiveness influence motivation: everything to gain versus everything to lose

We found that the effects on subsequent motivation of success and failure feedback are moderated by the extent to which individuals have been previously successful in promotion self‐ regulation (achieving their ideals) and prevention self‐ regulation (meeting their oughts). Specifically, we found that the more individuals are ideal congruent, the more their performance increases over time following success than failure feedback, whereas the more individuals are ought congruent, the more their performance increases over time following failure than success feedback. These findings have implications for research on the effects of feedback on motivation, as well as for the motivational significance of the expressions, ‘everything to gain’ and ‘everything to lose’.

Frog skin,time series,and other kinds of data: Nonisomorphic representation and analysis

Representational art is spatially congruent, or isomorphic, with objects in the world. In other words, they are the same in some important way. But not all representation is isomorphic. Data graphs are a type of nonisomorphic representation. A major goal of data graphs is to facilitate the rapid comprehension of differences or relations. This is done by providing a kind of analogy between something that can be “seen” (the relative heights of points) and some relevant information. This article discusses some rules about data graphing, then some new visualization tools are briefly critiqued.     

Attend to it now or lose it forever: selective attention,metacontrast masking,and object substitution

Metacontrast masking occurs when the visibility of a brief target stimulus is decreased by the subsequent appearance of another nearby visual stimulus. Early explanations of the phenomenon involved low-level mechanisms, but subsequent studies have suggested a role for selective attention. The results of three experiments presented here extend previous findings to the metacontrast paradigm. It is shown that the strength of metacontrast masking increases with the number of distractor items in a display, decreases when the target location is validly but not invalidly precued, and is eliminated when search for the target is efficient (pop-out search) but not when search is inefficient (serial search). A connection between metacontrast masking and object substitution masking is considered.
