FMRI of two measures of phonological processing in visual word recognition: ecological validity matters

Previous functional magnetic resonance imaging (fMRI) studies have investigated the role of phonological processing by utilizing nonword rhyming decision tasks (e.g., Pugh et al., 1996). Although such tasks clearly engage phonological components of visual word recognition, it is clear that decision tasks are more cognitively involved than the simple overt naming tasks, which more closely map onto normal reading behavior. Our research aim for this study was to examine the advantages of overt naming tasks for fMRI studies of word recognition processes. Process models are presented to highlight the similarities and differences between two cognitive tasks that are used in the word recognition literature, pseudohomophone naming (e.g., pronounce BRANE) and rhyming decision (e.g., do LEAT and JEAT rhyme?). An fMRI study identified several differences in cortical activation associated with the differences observed in the process models. Specifically, the results show that the overt naming task involved the insular cortex and inferior frontal gyrus, whereas the rhyming decision task engaged the temporal-parietal regions. It is argued that future fMRI research examining the neuroanatomical components of basic visual word recognition utilize overt naming tasks.     

Exploring the similarities and differences between person-centred and psychodynamic therapy

Person-centred therapy is compared to the psychodynamic approach defined by Hans Strupp and Jeffrey Binder. Their broad-based time-limited version is chosen because it is a precise manual ofhow to practise that has been assembled from 30 years of research and practice experience. It is demonstrated that person-centred practice and theory are psychodynamic in a general psychoanalytic sense because they refer to unconscious processes. Furthermore, it is proposed that person-centred practice could be enriched by reconsidering the differences to and similarities with psychodynamic therapy, thereby establishing greater clarity about each form of practice and further defining the boundary between these similar forms of relationship and feeling-oriented work.     

Predicting attempts and sustained cessation of smoking after the introduction of workplace smoking bans

Examined predictors of smoking cessation attempts and predictors of the outcome of those attempts after the introduction of a workplace smoking ban. Smokers were surveyed in the month before the ban came into force, and variables collected at that time were used to predict outcomes 6 months later. Data from 491 respondents who were smokers at the time of the initial survey were used, and a set of potential predictor variables was chosen on both theoretical and empirical grounds. Making a cessation attempt was predicted by the strength of desire to quit and, to less extent, by not having been subject to extensive restrictions on smoking before the mandated ban, having tried to quit before, perceiving oneself high in ability to quit, and being worried about smoke at work. For the outcome of cessation attempts among those who tried, success was best predicted by low levels of a composite habit strength variable and, to less extent, by desire to quit, no previous attempts to quit, the existence of social supports for quitting, and educational status. Although cognitive variables were important in predicting attempts, they played only a minor role in predicting maintenance. Behavioral and environmental variables contributed slightly to prediction of attempts and strongly to prediction of maintenance.     

Popular Politics and the Clinton/Lewinsky Affair: The Implications for Leadership

The Clinton/Lewinsky scandal unfolded in an era of "new media" politics that presented fresh and often unanticipated challenges for presidential leadership. New media actors, such as call-in talk radio and TV hosts, tabloid journalists, and Internet gossip columnists, played a significant role in scandal politics. They influenced the framework within which stories were reported and perceived by the public. New media channels, in particular, framed the events leading up to the presidential impeachment in terms of dramatic, prime time–style entertainment. This entertainment news frame allowed citizens to compartmentalize their perceptions of President Clinton as a leader versus a private individual involved in a sex scandal. Media Politics can explain, at least in part, President Clinton's strong job performance evaluations in the midst of one of the most publicized political scandals of the century.

Eating Disorder Examination Questionnaire (EDE-Q): norms for young adult women

In order to establish norms for the Eating Disorder Examination Questionnaire (EDE-Q) among young adult women, the questionnaire was administered to a large general population sample of women aged 18-42 yr in the Australian Capital Territory (ACT) region of Australia. Normative data were derived for EDE-Q subscales and for the occurrence of specific eating disorder behaviours, for each of five age bands (18-22, 23-27, 28-32, 33-37, 38-42 yr). Mean scores (SDs) for the Restraint, Eating Concern, Weight Concern and Shape Concern subscales for the total sample (n = 5,255) were, respectively, 1.30 (1.40), 0.76 (1.06), 1.79 (1.51) and 2.23 (1.65). The mean global score was 1.52 (1.25). The regular occurrence of objective and subjective overeating episodes was reported by 10.6% and 12.7% of participants, respectively. The regular use of self-induced vomiting, laxative misuse, and use of diuretics, was reported by 1.4%, 1.0%, and 0.3%, of participants, respectively, while 2.2% of participants reported regularly using diet pills. "Extreme dietary restraint" and "excessive exercise" were reported by 3.4% and 4.9% of participants, respectively. Both attitudinal and behavioural features of eating disorder psychopathology tended to decrease with increasing age. These data will inform researchers intending to use the EDE-Q in epidemiological studies.     

A longitudinal analysis of friendships and substance use: bidirectional influence from adolescence to adulthood

The reciprocal relation between deviant friendships and substance use was examined from early adolescence (age 13-14) to young adulthood (age 22-23). Deviance within friendships was studied using direct observations of videotaped friendship interaction and global reports of deviant interactions with friends as well as time spent with friends. Substance use was assessed through youth self-report at all time points. Multivariate modeling revealed that substance use in young adulthood is a joint outcome of friendship influence and selection processes. In addition, substance use appears to influence the selection of friends in late adolescence. Findings suggest that effective preventions should target peer ecologies conducive to substance use and that treatment should address both the interpersonal underpinnings and addiction processes intrinsic to chronic use, dependence, and abuse.     

Substance use risk across three generations: the roles of parent discipline practices and inhibitory control.

This study used 3 generations and 21 years of prospective data to test models of intergenerational transmission of substance use and substance use risk. Thus, the study extends prior studies in the field that have focused predominantly on substance abuse. The association between the grandparental generation's (G1 mother and father) and the parental generation's (G2 father) alcohol use and illicit drug use was hypothesized to be mediated by G2's poor inhibitory control. Additionally, G1's poor discipline of G2 was hypothesized to be directly associated with G2's substance use as well as to partially mediate the association between G1's substance use and G2's inhibitory control. In turn, G2's substance use in late adolescence was expected to be associated with its offspring's (G3) poor inhibitory control at age 3 years. Findings partially supported the predictions and varied by substance. For alcohol use, only cross-generational associations in use were found. For illicit drugs, both poor inhibitory control and poor discipline played some mediational role in cross-generational use.     

Homophone effects in visual word recognition depend on homophone type and task demands.

This experiment examined how the characteristics of homophones and their mates influence homophone effects, as a function of task demands. Two types of homophones were presented: 1) low-frequency homophones with higher-frequency mates that are not animal names (e.g., maid--made), and 2) low-frequency homophones with mates that are, on average, of equivalent frequency and are animal names (e.g., foul--fowl). We observed a double dissociation: In the lexical decision task (LDT), there was a homophone effect for the first type of homophones but not for the second, whereas in the semantic categorization task (SCT) the opposite was true. These results suggest that in these tasks the effects of homophony arise when the homophone's mate creates competition in terms of the type of processing emphasized in the task, namely, orthographic processing in the LDT and semantic processing in the SCT.     

Children's understanding of advertising: an investigation using verbal and pictorially cued methods

Conflicting results on children's understanding of advertising may stem from differences in research methods. Most studies are conducted using interviewing techniques, employing only verbal questioning. In the present study, 136 children of two age groups (7 and 10 years) were first asked what advertising was for and, after responding, shown depictions of possible reasons. The results indicate that although older children are more likely than younger ones to understand that advertising seeks to promote selling, pictorial cues allow a much larger proportion of all children to indicate their understanding than verbal questioning does on its own, with younger children especially showing improvement. Thus, seven‐year‐olds seem to have an implicit understanding of the persuasive intent of advertising that they are unable to articulate in response to investigators' questions. Multiple methods appear to offer a means of evaluating the level of sophistication in children' understanding of advertising. Copyright © 2007 John Wiley & Sons, Ltd.
