Inattentive and noninattentive ADHD children: Do they constitute a unitary group?

Teacher-rated ADHD and normal control children were administered a continuous performance test (CPT), and were then further subdivided based upon the presence or absence of objectively assessed attentional deficits. In addition, children were assessed using several measures of cognitive and behavioral functioning. Attentional deficits were signficantly more prevalent among the ADHD group, but about half of the ADHD children showed no evidence of objectively assessed attentional dysfunction. Further group analyses indicated that ADHD children with objectively assessed attentional dysfunction appeared cognitively impaired, while ADHD children without objective evidence of attentional dysfunction had more conduct problems. CPT inattention was not related to the presence of cognitive impairments or conduct problems in the control group. These data must be considered preliminary because teacher ratings were the only source of diagnosis and a single measure of inattention was used. However, they suggest that two subtypes of ADHD children can be identified, one characterized by inattention and learning problems, and the other by conduct problems.The authors gratefully acknowledge the assistance of Sister Hildegard Kogler and the St. Francis DeSales School, and the parents and children who participated in this study.     

Phonological encoding and ideographic reading by the disconnected right hemisphere: Two case studies

The mute disconnected right hemispheres (RHs) of two commissurotomy patients are able to understand spoken words and read printed words by matching them with pictures of the objects named. In this paper we report the results of five experiments. The RH of one patient could “evoke the sound image” of a word to the extent of matching two pictures with homonymous names (experiment 1) or with rhyming names (experiment 2) without being able to name either one. This transformation of picture to covert sound does not depend on orthographic similarity of word ends as a clue to homonymy or rhyme, nor does it improve with short-term learning. Yet neither RH can translate print into sound by matching a spelled word with a picture that has a rhyming name (experiment 3) or by matching two orthographically dissimilar rhymes, be they meaningful (experiment 4) or nonsense words (experiment 5). We suggest that these RHs read “ideographically,” recognizing words directly as visual gestalts without intermediate phonetic recoding or grapheme-to-phoneme translation.     

"Why is it that I see everything differently?" Reading a 1933 letter from Paula Heimann to Theodor Reik

A letter from Paula Heimann to her training analyst, Theodor Reik, written shortly before her emigration from Berlin to London, sheds light on some of the technical controversies and personal animosities that shaped psychoanalytic clinical discourse in the early 1930s, as well as on Heimann's subsequent development as a clinician. A close reading of this letter highlights several distinctive aspects of psychoanalytic training and demonstrates the transgenerational transmission of psychoanalytic ideas.     

The Central Role of Group-Based Hatred as an Emotional Antecedent of Political Intolerance: Evidence from Israel

In recent years, political scientists have shifted the focus of explaining political phenomena from the purely cognitive perspective to an integrated emotion-cognition one. Yet most studies which examine antecedents of political intolerance ignore the potential role played by "gut feelings" or group-based negative emotions in endorsing those attitudes. Moreover, even the few studies that deal with emotions and intolerance concentrate exclusively on the role of groups of emotions (positive vs. negative, dispositional vs. surveillance) or on basic emotions (anger or fear) and ignore the potential influence of more complex discrete emotions like hatred on political intolerance. Hence, the main goal of this study was to create a deeper understanding regarding the role of discrete negative emotions in increasing political intolerance among different groups of individuals in different contexts. In order to do so, the relations between political intolerance and three group-based negative emotions (hatred, anger, and fear) were tested by means of four large-scale nationwide surveys. Within the surveys, various intolerance measurement methods were used in various contexts (wartime vs. no-war/routine periods) and among individuals with different levels of political sophistication. Results, obtained via multiple regression analysis and structural equation modeling, show that: (1) Group-based hatred is the most important antecedent of political intolerance even when controlling for important intolerance inducers such as perceived threat. (2) Other group-based negative emotions like anger or fear influence political intolerance wholly through the mediation of hatred or perceived threat. (3) The role of group-based hatred in inducing political intolerance is more substantial in the face of heightened existential threat and among unsophisticated individuals than among sophisticated ones.     

The effects of bilateral presentations on lateralized lexical decision

We investigated how lateralized lexical decision is affected by the presence of distractors in the visual hemifield contralateral to the target. The study had three goals: first, to determine how the presence of a distractor (either a word or a pseudoword) affects visual field differences in the processing of the target; second, to identify the stage of the process in which the distractor is affecting the decision about the target; and third, to determine whether the interaction between the lexicality of the target and the lexicality of the distractor ("lexical redundancy effect") is due to facilitation or inhibition of lexical processing. Unilateral and bilateral trials were presented in separate blocks. Target stimuli were always underlined. Regarding our first goal, we found that bilateral presentations (a) increased the effect of visual hemifield of presentation (right visual field advantage) for words by slowing down the processing of word targets presented to the left visual field, and (b) produced an interaction between visual hemifield of presentation (VF) and target lexicality (TLex), which implies the use of different strategies by the two hemispheres in lexical processing. For our second goal of determining the processing stage that is affected by the distractor, we introduced a third condition in which targets were always accompanied by "perceptual" distractors consisting of sequences of the letter "x" (e.g., xxxx). Performance on these trials indicated that most of the interaction occurs during lexical access (after basic perceptual analysis but before response programming). Finally, a comparison between performance patterns on the trials containing perceptual and lexical distractors indicated that the lexical redundancy effect is mainly due to inhibition of word processing by pseudoword distractors.     

Harnessing the need for immediate gratification: cognitive reconstrual modulates the reward value of temptations

Many of us succumb to temptations, despite knowing that we will later regret doing so. How can such behavior be avoided? In three studies, the authors tested the hypothesis that reconstruing temptation as a test of a valued internal quality ("willpower") would decrease the tendency to succumb by reducing the appeal of the temptation. In Study 1, participants who construed a challenging handgrip task as a test of willpower resisted the temptation to terminate the painful task longer than participants who did not. In Study 2, participants performed a handgrip task twice. Only participants who changed their construal of the task into a test of willpower improved their performance. In Study 3, participants took a timed math test while being tempted by comedy clips. Participants who reconstrued the situation as willpower test compared with participants who did not, (a) enjoyed the videos less, and (b) were better able to resist the tempting videos. These studies demonstrate that cognitive reconstrual can be used to modify reward contingencies, so that succumbing to temptation becomes less appealing, and resisting temptation becomes more appealing.     

Analysis of the Mediating Effect of Personal-Psychological Variables on the Relationship Between Socioeconomic Status and Political Participation: A Structural Equations Framework

The goal of this research was to test whether the relationship between socioeconomic status and political participation is direct or mediated by personal variables such as self-esteem, locus of control, and political efficacy, and to detect how such a mediating process might operate if it exists. Two forms of participation, namely active political participation and the more passive psychological involvement of citizens in the democratic process, were treated as separate but related facets of participation. Four competing models were advanced and tested. The data were collected from 434 citizens in the north of Israel who were interviewed by questionnaire. The analysis was performed by structural equations modeling with LISREL VIII. The findings show that the relationship between socioeconomic status and political participation can be better understood as being mediated by personal variables rather than direct. This is demonstrated by the many nonsignificant paths in the direct model. The findings also reveal that active political participation and psychological involvement are distinct but related constructs, where involvement leads to active participation. In addition, all research variables were related more strongly to psychological involvement than to active political participation. The findings are discussed in terms of their implications for future research on political participation.     

A rational look at the emotional stroop phenomenon: a generic slowdown, not a stroop effect

The role of Stroop processes in the emotional Stroop effect was subjected to a conceptual scrutiny augmented by a series of experiments entailing reading or lexical decision as well as color naming. The analysis showed that the Stroop effect is not defined in the emotional Stroop task. The experiments showed that reading, lexical decision, and color naming all are slower with emotional words and that this delay is immune to task-irrelevant variation and to changes in the relative salience of the words and the colors. The delay was absent when emotional and neutral words appeared in a single block. A threat-driven generic slowdown is implicated, not a selective attention mechanism associated with the classic Stroop effect.     

Early development of subcortical regions involved in non-cued attention switching

This study examined the cognitive and neural development of attention switching using a simple forced-choice attention task and functional magnetic resonance imaging Fourteen children and adults made discriminations among stimuli based on either shape or color. Performance on these trials was compared to performance during blocked trials requiring all color or all shape discriminations. Magnetic resonance echo planar images were acquired during performance of the task. Both children and adults showed robust bilateral activity of the caudate nucleus when switching attention between color and shape discriminations that correlated negatively with mean response latency on these trials. However, neither switching costs nor caudate activity correlated with age, suggesting early development of the underlying neural circuitry involved in switching between salient stimulus sets. Overall, children and adults differed in performance and patterns of brain activity on the task, with adults responding more accurately and faster than children, and recruiting more prefrontal and parietal regions. These results suggest an important role of subcortical regions (i.e. caudate nucleus) in non-cued attention switching, with increasing recruitment of cortical regions with age.     

Explaining Normative Versus Nonnormative Action: The Role of Implicit Theories

The current research investigates what motivates people to engage in normative versus nonnormative action. Prior research has shown that different emotions lead to different types of action. We argue that these differing emotions are determined by a more basic characteristic, namely, implicit theories about whether groups and the world in general can change. We hypothesized that incremental theories (beliefs that groups/the world can change) would predict normative action, and entity theories (beliefs that groups/the world cannot change) as well as group identification would predict nonnormative action. We conducted a pilot in the context of protests against a government plan to relocate Bedouin villages in Israel and a main study during the Israeli social protests of the middle class. Results revealed three distinct pathways to collective action. First, incremental theories about the world predicted hope, which predicted normative action. Second, incremental theories about groups and group identification predicted anger, which also predicted normative collective action. Lastly, entity theories about groups predicted nonnormative collective action through hatred, but only for participants who were highly identified with the group. In sum, people who believed in the possibility of change supported normative action, whereas those who believed change was not possible supported nonnormative action.
