A test of the interactive effects of anxiety sensitivity and mindfulness in the prediction of anxious arousal, agoraphobic cognitions, and body vigilance

The present investigation sought to examine the interactive effects of anxiety sensitivity [AS; Reiss, S., & McNally, R. J. (1985). Expectancy model of fear. In S. Reiss, & R. R. Bootzin (Eds.), Theoretical issues in behavior therapy (pp. 107-121). San Diego: Academic Press] and mindfulness [Brown, K. W., & Ryan, R. M. (2003). The benefit of being present: Mindfulness and its role in psychological well-being. Journal of Personality and Social Psychology, 84, 822-848] in predicting panic-relevant processes. A community sample of 248 individuals participated in the study by completing a battery of self-report instruments. Consistent with prediction, the interaction between AS and mindfulness significantly predicted anxious arousal symptoms and agoraphobic cognitions, above and beyond the individual main effects, and did not significantly predict anhedonic depression symptoms. Contrary to prediction, the AS by mindfulness interaction did not significantly predict body vigilance. Theoretical implications are discussed and future directions are delineated.     

Emotional-vulnerability and mindfulness: a preliminary test of associations among negative affectivity, anxiety sensitivity, and mindfulness skills

This study evaluated associations between general (negative affectivity) and specific (anxiety sensitivity) factors that may relate to the mindfulness skill domains assessed by the Kentucky Inventory of Mindfulness Skills. Participants were 154 young adults (88 females; M(age) = 22.4 years, SD = 7.9) recruited from the community. Partially consistent with predictions, higher levels of negative affectivity were significantly associated with lower levels of Awareness, Acceptance, and Describe mindfulness skills, and higher levels of anxiety sensitivity were significantly associated with lower levels of Awareness and Acceptance mindfulness skills. Additionally, negative affectivity and anxiety sensitivity each demonstrated unique relations to participants' ability to experience the present state without evaluating or judging its content (Accept factor), after accounting for their shared variance, but only anxiety sensitivity demonstrated a unique association to the Act with Awareness factor independent of variance explained by negative affectivity. Findings are discussed in relation to theory and research on mindfulness processes.     

Frequency of verb use in young children who stutter

Several recent studies have suggested that young children who stutter (CWS) tend to show depressed lexical performance relative to peers. Given the developmental literature as well as several studies of verb processing in individuals who stutter, verbs may pose a particular challenge for this group. The purpose of the present study was to examine verb use in CWS. In theory, if young CWS differ in their production of verbs, this finding would partially explain the findings of studies that probed conversational vocabulary skills more generally. Fifteen CWS and 15 children who do not stutter (CWNS) participated in a play-based conversational sample with a parent. Samples were analyzed for the total number of verbs, the number of different verbs, and the proportion of general all-purpose (GAP) verbs within the samples. CWS produced significantly fewer different verbs and total verbs than the CWNS. However, previously reported near-significant differences in utterance length between groups would appear to temper the robustness of this finding. The groups did not differ in the proportion of GAP verbs used, suggesting that the CWS did not over-rely on GAP verbs in conversational language production but rather used these verbs to the same extent as their peers. Educational objectives: As a result of this activity, the participant will be able to: (1) relate the purpose and rationale for examining verb use in children who stutter (CWS); (2) summarize the procedures used to assess verb use and GAP verb use in the present study; (3) explain the findings of the present study; (4) relate findings to the extant literature on lexical diversity in CWS.     

Pronouncing novel graphemes: The role of consonantal context

In three experiments, we examined how readers learn and generalize new pronunciations for vowel graphemes. Children ages 6 1/2 to 9 (n = 97) and college students (n = 21) were taught a nonword that included a novel vowel pronunciation in the middle position (e.g., zuop is pronounced /zup/). They were then asked to pronounce other nonwords that contained the same vowel grapheme. Participants were more likely to use the taught pronunciation when the target item and the training item shared a consonant as well as a vowel than when they shared only the vowel. The new pronunciation was not significantly more likely to appear when the target shared the vowel and final consonant (rime) of the training stimulus than when it shared the initial consonant and vowel. We discuss implications for views of reading and its development.     

We saw it all along: visual hindsight bias in children and adults

Abstract— We traced the developmental origins and trajectory of the hindsight bias. Three-, 4-, and 5-year-old children and adults identified gradually clarifying images of degraded common objects on a computer. Half the time, observers did not know in advance what the object would become. The rest of the time, observers knew the object's identity in advance and estimated when a naive same-age peer would identify the clarifying object. In two experiments, children and adults demonstrated hindsight bias by using advance knowledge to overestimate their same-age peers' ability to identify the objects. The magnitude of this bias declined across age in one experiment, but remained relatively stable over age in the other experiment. These findings link developmental psychology and adult cognitive science.     

Susceptibility to memory distortion: how do we decide it has occurred?

When given suggestive information, some people can be led to believe that they had experiences that they did not actually have. For example, they may come to believe falsely that they got sick eating particular foods as children, and as a result of that belief they may avoid the foods. But how do we know that someone has developed a false belief or memory in this research? The criteria we choose when classifying whether someone has fallen for the suggestion are somewhat arbitrary. We reanalyze our prior data, using different criteria for deciding that a person fell for the suggestion (called a "believer") or did not (called a "non-believer"). Changing criteria obviously affects the percentage of people who are called susceptible and could conceivably affect the conclusions reached about that group. Comparisons between false memories and true memories could differ, too, depending on how memories are defined.     

Anxiety sensitivity interacts with marijuana use in the prediction of anxiety symptoms and panic-related catastrophic thinking among daily tobacco users

The present investigation evaluated whether anxiety sensitivity interacted with marijuana use in relation to the prediction of panic-relevant variables among young adult tobacco smokers (n=265). Approximately 73% of the sample was composed of current marijuana smokers, with 78.5% of this sub-sample using marijuana more than once per week. As expected, after covarying cigarettes per day, alcohol use, and negative affectivity, the interaction between marijuana use and anxiety sensitivity predicted anxiety symptoms and agoraphobic cognitions. Partially consistent with prediction, the interaction between frequency of marijuana use and anxiety sensitivity predicted only anxiety symptoms. These results are discussed in relation to better understanding the potential role of regular marijuana use and anxiety sensitivity for panic-relevant emotional vulnerability among regular tobacco smokers.     

Shared targets for aggression by early adolescent friends

Similarity in early adolescent friends' general aggressiveness is well known, but questions remain regarding the degree to which friends aggress against the same victims. The authors examined this by administering the newly created Dyadic Aggression and Victimization Inventory to 417 sixth- through eighth-grade boys and girls (53%). Friends were found to share more targets for aggression than nonfriends, even after general levels of aggression were controlled (all ps < .05). Moreover, greater sharing of targets with friends relative to nonfriends was more pronounced among aggressive youths than nonaggressive youths, especially among aggressive youths' best friends relative to their other friends. Generally, these findings were similar across boys and girls as well as among older and younger youths. Implications of these findings and directions for future research are discussed.     

The effect of long-term working memory through personalization applied to free recall: Uncurbing the primacy-effect enthusiasm

In this study, a personalization method (Guida, Tardieu, & Nicolas, European Journal of Cognitive Psychology, 21: 862–896 2009) was applied to a free-recall task. Fifteen pairs of words, composed of an object and a location, were presented to 93 participants, who had to mentally associate each pair and subsequently recall the objects. A 30-s delay was introduced on half of the trials, the presentation rate was manipulated (5 or 10 s per item), and verbal and visuospatial working memory tests were administered to test for their effects on the serial curve. Two groups were constituted: a personalized group, for whom the locations were well-known places on their university campus, and a nonpersonalized group, for whom the locations did not refer to known places. Since personalization putatively operationalizes long-term working memory (Ericsson & Kintsch, Psychological Review, 102: 211–245 1995)—namely, the capacity to store information reliably and rapidly in long-term memory—and if we take a dual-store approach to memory, the personalization advantage would be expected to be greater for pre-recency than for recency items. Overall, the results were compatible with long-term working memory theory. They contribute to validating the personalization method as a methodology to characterize the contribution of long-term memory storage to performance in working memory tasks.     

Improving the Performance of Failing Students by Overcoming Their Self-Serving Attributional Biases

The causal impact of attributions on academic performance was examined by changing low-scoring students' attributions regarding their poor performances. Initially, when students who were failing a college course identified the cause of the performance, they emphasized external, uncontrollable causes. Because these self-serving attributions could have perpetuated poor performance on subsequent examinations, students in the experimental condition were exposed to information that suggested that grades in college are caused by internal, controllable factors such as effort and motivation. As predicted, on subsequent tests and on the final examination, these students earned higher grades than control students who received no attributional information. These findings lend support to an attributional model of academic achievement and also suggest that educational interventions that shift attributions away from a self-serving pattern to a performance-facilitating pattern may improve academic outcomes.
