Perfectionism, beliefs, and adjustment in dating relationships

Two studies examined the extent to which dimensions of perfectionism are associated with indices of relationship beliefs, behaviors, and dyadic adjustment. In Study 1, 69 students in dating relationships completed the Multidimensional Perfectionism Scale (MPS) and a multidimensional measure of relationship beliefs. In addition, partici-pants completed self-report measures of positive and negative relationship behaviors, and global measures of liking and loving. In Study 2, 91 students in dating relation-ships completed a battery of measures including the MPS and scales assessing perfec-tionism cognitions and perfectionistic self presentation. They also completed mea-sures of dyadic adjustment and limerence (i.e., intense, obsessive low with fears of rejection). Collectively, the findings indicated that individuals with high levels of self-oriented perfectionism and other-oriented perfectionism have stronger relationship beliefs in the areas of communication, trust, and support, suggesting that these perfec-tionists have high relationship standards in these particular areas. Although social prescribed perfectionism had little association with specific relationship beliefs, so-cially prescribed perfectionism was associated with a tendency to display destructive relationship responses (i.e., exit, neglect, and insensitivity), lower dyadic adjustment, and various aspects of limerence, including obsessive preoccupations and emotional dependence on the dating partner. Perfectionistic self-presentation and perfectionism cognitions were also linked with aspects of limerence. The results suggest that inter-personal aspects of perfectionism are associated with self-defeating tendencies in dating relationships.

Inhibitory attentional control in patients with frontal lobe damage

The performance of a group of frontal lobe lesion and a group of frontal lobe dementia patients was compared with the performance of their respective matched normal control groups on two tests of inhibitory attentional control-the stop-signal reaction time task and a negative priming task. Both patient groups responded significantly slower than their respective normal control groups, but they showed only marginally significant selective impairments on the measures of inhibition. The data suggest that the specific inhibitory processes evaluated by these two tests are, in general, spared in patients with focal frontal lobe lesions or frontal lobe degeneration.     

Perfectionism,Stress, Daily Hassles,Hopelessness, and Suicide Potential in Depressed Psychiatric Adolescents

The current study examined dimensions of perfectionism, stress, hopelessness, and suicidality in a sample of adolescent psychiatric patients diagnosed with depression. This study evaluated the unique contribution of perfectionism in predicting suicidality after considering other predictors (i.e., hopelessness, depression) and it also examined the diathesis-stress model of perfectionism and suicide. A sample of 55 adolescents (41 females, mean age = 15.53, 25.5 % ethnic/racial minorities) who were psychiatric patients completed measures including the Child-Adolescent Perfectionism Scale, subjective and objective indices of life stress, daily hassles, depression, hopelessness, suicide ideation, prior attempts and suicide potential. In addition, other informants (i.e., adolescents’ parents) completed a diagnostic interview and an interview assessing major stressful experiences. Socially prescribed perfectionism (i.e., the perception that others require perfection of oneself) predicted concurrent levels of suicide potential and this association with suicide potential held even after controlling for the variances accounted for by depression and hopelessness. Hierarchical regression analyses provided partial support for the diathesis-stress model, that is, socially prescribed perfectionism interacted with daily hassles to predict concurrent suicide potential even after controlling for depression, hopelessness, and prior suicide attempt. Together, these findings suggest that socially prescribed perfectionism acts as a vulnerability factor that is predictive of suicide potential or risk among clinically depressed adolescents.     

Word skipping during sentence reading: effects of lexicality on parafoveal processing

Two experiments examined how lexical status affects the targeting of saccades during reading by using the boundary technique to vary independently the content of a letter string when seen in parafoveal preview and when directly fixated. Experiment 1 measured the skipping rate for a target word embedded in a sentence under three parafoveal preview conditions: full preview (e.g., brain–brain), pseudohomophone preview (e.g., brane–brain), and orthographic nonword control preview (e.g., brant–brain); in the first condition, the preview string was always an English word, while in the second and third conditions, it was always a nonword. Experiment 2 investigated three conditions where the preview string was always a word: full preview (e.g., beach–beach), homophone preview (e.g., beech–beach), and orthographic control preview (e.g., bench–beach). None of the letter string manipulations used to create the preview conditions in the experiments disrupted sublexical orthographic or phonological patterns. In Experiment 1, higher skipping rates were observed for the full (lexical) preview condition, which consisted of a word, than for the nonword preview conditions (pseudohomophone and orthographic control). In contrast, Experiment 2 showed no difference in skipping rates across the three types of lexical preview conditions (full, homophone, and orthographic control), although preview type did influence reading times. This pattern indicates that skipping not only depends on the presence of disrupted sublexical patterns of orthography or phonology, but also is critically dependent on processes that are sensitive to the lexical status of letter strings in the parafovea.     

On the importance of being first: Serial order effects in the interaction between action plans and ongoing actions

When we plan sequences of actions, we must hold some elements of the sequence in working memory (WM) while we execute others. Research shows that execution of an action can be delayed if it partly overlaps (vs. does not overlap) with another action plan maintained in WM (partial repetition cost). However, it is not known whether all features of the action maintained in WM interfere equally with current actions. Most serial models of memory and action assume that interference will be equal, because all action features in the sequence should be activated to an equal degree in parallel; others assume that action features earlier in the sequence will interfere more than those later in the sequence, because earlier features will be more active. Using a partial repetition paradigm, this study examined whether serial position of action features in action sequences maintained in WM have an influence on current actions. Two stimulus events occurred in a sequence, and participants planned and maintained an action sequence to the first event (action A) in WM while executing a speeded response to the second event (action B). Results showed delayed execution of action B when it matched the first feature in the action A sequence (partial repetition cost), but not when it matched the last feature. These findings suggest that serial order is represented in the action plan prior to response execution, consistent with models that assume that serial order is represented by a primacy gradient of parallel feature activation prior to action execution.     

Perfectionism,Type A Behavior,and Self-Efficacy in Depression and Health Symptoms among Adolescents

The current study examined the associations among dimensions of perfectionism, Type A behavior, self-efficacy, distress, and health symptoms in high school students. A sample of 73 high school students (34 boys, 39 girls) completed measures of self-oriented perfectionism, socially prescribed perfectionism, Type A behavior, self-efficacy, depressive symptoms, and psychosomatic symptoms. Correlational analyses found that self-oriented perfectionism was marginally related to Type A behavior. Students with elevated levels of depressive symptoms were also characterized by self-oriented perfectionism, Type A behavior, low self-efficacy, and health symptoms. In addition, health symptoms were linked with low self-efficacy. Simultaneous entry of several variables into a regression analysis found that significant unique predictors of depression were low self-efficacy and elevated self-oriented perfectionism. Similarly, a regression analysis found that low self-efficacy and high self-oriented perfectionism were unique predictors of health symptoms. The findings highlight the distinctions between the perfectionism and the Type A constructs, and support self-regulation models of depression and physical symptoms that include an emphasis on excessive perfectionistic standards and low self-efficacy. We discuss the need for preventive interventions designed for perfectionistic adolescents with low self-efficacy.     

The logic of Simpson’s paradox

There are three distinct questions associated with Simpson’s paradox. (i) Why or in what sense is Simpson’s paradox a paradox? (ii) What is the proper analysis of the paradox? (iii) How one should proceed when confronted with a typical case of the paradox? We propose a “formal” answer to the first two questions which, among other things, includes deductive proofs for important theorems regarding Simpson’s paradox. Our account contrasts sharply with Pearl’s causal (and questionable) account of the first two questions. We argue that the “how to proceed question?” does not have a unique response, and that it depends on the context of the problem. We evaluate an objection to our account by comparing ours with Blyth’s account of the paradox. Our research on the paradox suggests that the “how to proceed question” needs to be divorced from what makes Simpson’s paradox “paradoxical.”     

The Effects of Decision Outcome Dispersion Upon Organizational Decision Making

The effects of varying decision outcome dispersion on organizational decision making were investigated under individual and group decision making conditions. Thirty-six female and pg]36 male subjects made decisions for organizational decision scenarios in which outcomes affected primarily the decision maker, people other than the decision maker, or a group of which the decision maker was a member. Subjects rated their levels of perceived risk and confidence in their decisions and made decisions within a simulated context of either a small or a large organization. Results indicated that subjects perceived significantly less risk and more confidence in their decisions when outcomes affected primarily themselves rather than others regardless of whether the decisions were made individually or by a group. Males perceived their decisions as significantly more risky than females. Induced organizational size did not significantly influence decision making.
