Do self-statements enhance the effectiveness of virtual reality exposure therapy? A comparative evaluation in acrophobia.

There is a clear need for more detailed analysis of the role of cognitive self-statements in virtual reality exposure therapy (VRET). To date, no research on this topic has been done. The primary aim of this study was to investigate whether coping self-statements would enhance the effectiveness of VRET. In a randomized crossover design, 26 patients with acrophobia (DSM-IV diagnosis of specific phobia) were randomly assigned to two sessions of VRET followed by two sessions of VRET plus coping self-statements, or the other way around: first two sessions of VRET plus coping self-statements followed by two sessions of VRET. Results showed that VRET, regardless of addition of coping self-statements, decreased anxiety of heights, decreased avoidance of height situations, and improved attitudes towards heights. However, at 6-month follow-up, most gains during treatment were not fully retained.     

Does mental practice still enhance performance? A 24 Year follow-up and meta-analytic replication and extension

ObjectivesMotor imagery (MI) is a dynamic mental state during which the representation of a given motor movement is rehearsed in working memory without overt motor output. Mental practice (MP; also known as motor imagery practice) is the systematic application of MI for the cognitive rehearsal of a task in the absence of overt physical movements. Although MP is known to enhance skilled performance, debate still exists about the magnitude and moderators of these imagery effects. Against this background, and amid concerns about the “reproducibility crisis” in psychology, it seems timely to revisit, update and extend a key meta-analysis of MP effects published over two decades ago – namely, that of Driskell, Copper, and Moran (1994). To this end, the present paper reports a methodological replication of the Driskell et al’s (1994) meta-analysis of MP effects.Design & methodIncluded are 37 studies on MP effects published between 1995 and 2018. Nine factors were selected to examine the extent to which they moderate the effectiveness of mental practice, providing a window into the conditions under which mental practice is most effectively implemented. Practice Type (Mental or Physical), Expertise, Duration of practice (both program and session), Task Type, and Control Type were retained as factors of interest from the original Driskell et al. (1994) meta-analysis. In order to further explore the nuance of mental practice implementation, we additionally examined the Imagery Type, the Performance Measure used, Activity Type (team versus individual activities) and the Setting of the intervention.ResultsFollowing publication bias analyses, our results confirm that overall, MP has a small but significant positive effect on performance (r = 0.131). Moderators of this beneficial effect were MP duration, type of task and type of imagery used.ConclusionsWe conclude that MP has an enduring positive influence on performance.     

Do changes in the subjective experience of recognition over time suggest independent processes?

Two experiments examined the nature of recognition memory by asking how subjective reports of remembering change over time. In Experiment 1, participants were asked to report their experience of remembering using the well‐known remember–know–guess procedure. Estimates of recollection declined over a 14‐day period, but estimates of familiarity remained constant, suggesting that the processes are independent. In Experiment 2, participants were asked to report their confidence in their recognition decisions. Subjective reports of confidence were analysed via receiver operating characteristics and also indicated different rates of decline for recollection and familiarity. Superficially, the data appear to support a dual‐process account of recognition, but close inspection shows the data to be consistent with a simple signal detection model. The conclusion is that although the phenomenal experience of remembering changes over time this is most likely to be predicated on a single process.     

Lexical access codes in visual word recognition: are the joint effects of context and stimulus quality diagnostic?

Is it possible to identify when lexical access in visual word recognition is based on an orthographic code and when it is based on a phonological code? Some researchers have argued that the joint effects of semantic context and stimulus quality in lexical decision are diagnostic. Their argument is that when phonological recoding is employed, it serves to keep the effects of stimulus quality and context from interacting. Semantic context and stimulus quality are therefore predicted to have additive effects on RT. In contrast, when lexical access is not mediated by a phonological recoding stage, then the effect of stimulus quality interacts with context, as commonly seen in the literature. A strong test of these claims was devised in which participants were forced to use phonological recoding for the purpose of lexical access. An interaction between context and stimulus quality was observed. This finding is taken as evidence that the joint effects of semantic context and stimulus quality are not diagnostic with respect to the nature of the lexical access code (i.e., orthographic versus phonological) for readers of English.     

Does ignoring lead to worse evaluations? A new explanation of the stimulus devaluation effect

Affective evaluation of stimuli just seen in visual search tasks has been shown to depend on task-relevant stimulus configuration (Raymond, Fenske, & Tavassoli, 2003): Whereas targets and novel stimuli were evaluated similarly, distractors were devaluated. These results were explained by an inhibition-based account of the influence of selective attention on emotion. In the present experiments, we demonstrated that stimulus devaluation might not be a consequence of attentional inhibition. By simply instructing participants to react to an accepted or rejected stimulus in the visual search task of Experiment 1, we found distractor devaluation in the first case and target devaluation in the second case. We conclude that devaluation of stimuli is mediated by the affective connotation implied by response labels and instructions. This was confirmed in Experiment 2: To-be-ignored stimuli were not devaluated when participants knew that those stimuli would become task-relevant during the experiment.     

Does the courage measure really measure courage? A theoretical and empirical evaluation

Courage has seen an explosion of research in all branches of psychology, and the most popular measure is Norton and Weiss’s the courage measure (CM). Despite widespread use, limited investigations into its psychometric properties and validity have been performed. To ensure the strength of findings drawn from the scale, the current study performs a theoretical, psychometric, and empirical analysis of the CM. The results demonstrate that the CM has theoretical concerns stemming from the operational definition of courage used during its creation, and may not actually measure courage. Also, the CM was shown to consist of two dimensions separated by regular and reverse coding. Next, the scale demonstrated slight concerns with method effects, and its construct validity was analyzed. Together, the results demonstrate that the CM would benefit from the removal of reverse coded items, and may actually gage persistence despite fear rather than courage.     

Does the nature of the experience influence suggestibility? A study of children's event memory

Two experiments examined the effects of event modality on children's memory and suggestibility. In Experiment 1, 3- and 5-year-old children directly participated in, observed, or listened to a narrative about an event. In an interview immediately after the event, free recall was followed by misleading or leading questions and, in turn, test recall questions. One week later children were reinterviewed. In Experiment 2, 4-year-old children either participated in or listened to a story about an event, either a single time or to a criterion level of learning. Misleading questions were presented either immediately or 1 week after learning, followed by test recall questions. Five-year-old children were more accurate than 3-year-olds and those participating were more accurate than those either observing or listening to a narrative. However, method of assessment, level of event learning, delay to testing, and variables relating to the misled items also influenced the magnitude of misinformation effects.     

Does parental autonomy support mediate the relation between parent and infant executive function? A study of mothers and fathers in the Netherlands and China

Parenting skills, such as Autonomy Support (AS), have been proposed as a potential mechanism explaining the intergenerational contiguity of Executive Function (EF). However, few studies have focused on mothers and fathers among non-Western families. The current study investigated the role of maternal and paternal AS in the relation between parental EF and infant EF at 14 months of age among 123 Dutch and 63 Chinese first-time mothers and fathers and their infants. Multiple-group structural equation models were built for mothers and fathers separately with country as a grouping variable. Results showed that parental AS did not mediate the relation between parent EF and infant EF at 14 months. Mean-level differences were found in parental AS, maternal EF, and infant inhibition across countries, while no country differences were found in the relation between parent EF, AS and infant EF. Our findings suggested that individual differences in early EF may not be stable enough to be reliably predicted from parental factors across the Netherlands and China.     

Does frontal brain activity mediate the effect of depression prevention in adolescents? A pilot study

We investigated whether (a) depression prevention was associated with depressive symptoms and medial-frontal alpha asymmetry in adolescents; (b) alpha asymmetry mediated the association between participation in a prevention program and depressive symptoms; and (c) gender affects these associations. In our randomised control group study, we compared a universal prevention program (n = 40 adolescents, 14 females) with a non-intervention control condition (n = 39 adolescents, 20 females) in German secondary school students (mean age: 13.53 years, SD = 0.53). We collected data at baseline, post-intervention, 6-month, and 12-month follow-up using the Self-Rating Questionnaire for Depressive Disorders (SBB-DES) and resting medial-frontal alpha activity on F3 and F4. We found that girls benefitted from participating in the prevention program in regards to their depressive symptoms at 12-month follow-up but not alpha asymmetry. In boys, participation in the prevention program was associated with their alpha asymmetry at 6-month follow-up but not their depressive symptoms. Alpha asymmetry did not mediate the effects of the prevention program on depressive symptoms in either gender. Although participation in the prevention program was associated with both depressive symptoms and alpha asymmetry, those associations seem independent from each other. Possible explanations for this result pattern are discussed.     

Do positive illusions predict overconfidence in judgment? A test using interval production and probability evaluation measures of miscalibration

We address the question as to whether judgmental overconfidence, as assessed by probability miscalibration, is related to positive illusions about the self. We first demonstrate that judgmental overconfidence measured with interval production procedures can be considered a trait, due to correlations observed in miscalibration scores in two sets of general‐knowledge questions of varying difficulty administered at different times. In addition, the hard‐easy effect operated in different ways on overprecision and self‐placement of one's performance relative to others: The more difficult the calibration task, the greater the over precision but the greater the under placement of one's performance. Finally, there was no evidence that miscalibration was related to dispositional optimism and self‐efficacy. A second study extended these results by including further measures of disposition to experience positive illusions such as unrealistic optimism, a general tendency to consider oneself “better‐than‐average,” and two indexes of dispositional perception of control. The positive illusion measures showed considerable inter‐correlations, but did not correlate with miscalibration on the interval production task, and correlated negatively with optimism concerning societal risks. A final study replicated this pattern of findings, but showed that disposition to positive illusions did predict miscalibration on the same questions measured with a probability evaluation technique. Our research demonstrates that “overconfidence” is not a unitary construct, but a series of overlapping ones. Copyright © 2010 John Wiley & Sons, Ltd.     

What's in a word? A parametric study of semantic influences on visual word recognition

To what extent does semantic information play a functional role in visual word recognition? Theories of word recognition vary in the importance assigned to semantic information in visual lexical decision, with past research suggesting that the nature of the foils is a crucial determinant of semantic reliance. Here, we explored the conditions under which semantic variables influence lexical decision. Normal readers performed visual lexical decision tasks in which imageability and semantic priming were manipulated, with nonword foils varying systematically in their orthographic and phonological similarity to the real words. The effects of imageability and semantic priming increased in magnitude as nonword foils became progressively more wordlike. These findings provide a clear illustration of the flexible use of semantic information to support normal visual word recognition.     

Does phonological change play a role in the recognition of derived forms across modalities?

This study investigates the way in which phonological change during derivation influences the access of complex words in the on-line performance of English-speaking subjects during word recognition. Three visual lexical decision experiments were administered (cross-modal priming, visual priming and simple). Overall, the results showed that the forms which were subject to phonological change during derivation were always recognized significantly slower than those without phonological alterations. The results confirm the role of phonological change in accessing derived words. They also have important implications for a theory of lexical representation.     

Is the Narcissistic Personality Inventory still relevant? A test of independent grandiosity and entitlement scales in the assessment of narcissism

Some scholars have called for the replacement of the Narcissistic Personality Inventory (NPI) with more narrow scales measuring grandiosity and entitlement instead. In the current study, the authors examined the relations among the NPI and measures of grandiosity and entitlement, as well as in relation to a measure of the Five-Factor Model (FFM). The NPI manifested significant correlations with the alternative scales of entitlement and grandiosity and relatively similar patterns of correlations with the FFM traits. Of note, the NPI manifested significant incremental validity in the prediction of several FFM traits that are central to the conceptualization of narcissism. These findings suggest that some caution must be used before assuming that these lower-order scales can be used to replace the NPI in the assessment of narcissism.     

What can we recognize? A study of native-Dutch students' recognition of lecture material presented in English

Summary The study sets out to explore native-Dutch students' recognition of lecture material presented in English. Three types of statements were tested: topic, detail, and extraneous remarks. After seven days, not only was significant memory for meaning apparent, but students were also able to produce a high level of verbatim memory. No differences were found between topic and detail statements. Though memory for old extraneous remarks was no different from those for other types of statements, both paraphrases and new remarks were better rejected. Similarities and differences between this study and that of Kintsch and Bates (1977) are made and the role played by context in memory within real-life communication is discussed.     

Does the information content of an irrelevant source differentially affect spoken word recognition in younger and older adults?

To determine whether older adults find it difficult to inhibit the processing of irrelevant speech, the authors asked younger and older adults to listen to and repeat meaningless sentences (e.g., "A rose could paint a fish") when the perceived location of the masker (speech or noise) but not the target was manipulated. Separating the perceived location (but not the physical location) of the masker from the target speech produced a much larger improvement in performance when the masker was informational (2 people talking) than when the masker was noise. However, the size of this effect was the same for younger and older adults, suggesting that cognitive-level interference from an irrelevant source was no worse for older adults than it was for younger adults.     

Does thinking about the meaning of life make you happy in a religious and globalised world? A 75-nation study

This paper reports on a multilevel study of 75 nations, which tests two hypotheses that arose from considering Tolstoy's experience of thinking about the meaning and purpose of life. The globalisation-as-exacerbator hypothesis predicts that as globalisation increases, the relationship between thinking about the meaning and purpose of life and life satisfaction becomes more negative. The religiosity-as-buffer hypothesis predicts that as religiosity increases, the relationship between thinking about the meaning and purpose of life and life satisfaction becomes more positive. The results presented here support both hypotheses. We also found that it is religious attendance (not religious belief) that functions as a buffer in the relationship between thinking about the meaning and purpose of life and life satisfaction.     

Complex and underreported? A study into the prevalence of suicide by motor vehicle in the state of Queensland

While suicide is recognised as one of the leading causes of death in Australia, it is often presumed that fatal road crashes are primarily accidental in nature. However, international research has indicated that deliberate attempts at self-harm while driving may account for between 1.1% and 7.4% of road crashes. Despite the personal and financial costs associated with such events, few studies have examined the extent of motor vehicle suicides (MVS) or the circumstances surrounding such incidents in Australia. Given this, the current study reviewed coronial, police and toxicology findings of 762 motor vehicle fatalities in Queensland (Australia) during the period 2011 to 2015 to determine the frequency of confirmed cases and explore the prevalence (and characteristics) of possible MVS that remain undetected. In total, 22 confirmed cases were identified, and such events shared significant similarities with 14 possible events, including evidence of recent emotional upset, adversity and mental health diagnoses. In contrast, differences between the groups were limited to confirmed cases being more likely to involve males and contain a suicide note or evidence of past suicidality, while possible cases were more likely to involve a multiple vehicle impact with a truck. Importantly, crucial information regarding the deceased’s psychological state and life circumstances (e.g., psychological autopsy) was not reported in many cases. Corresponding qualitative analysis of the coroners final determination (between the two groups) revealed the occurrence of the word suicide to occur seven times (31.8%) among confirmed cases and five times (35.7%) for possible casers. Furthermore, the coroners final determination of intent to suicide was open or undetermined in six of the possible cases (43%), which further suggests a reluctance (or procedural uncertainty) to categorically identify MVS. The paper further reviews the main findings, illuminates core challenges associated with identifying MVS and proposes a need for future investigations to incorporate a more standardised and evidence-based approach in order to effectively identify such events.     

Does trait coping exist? A momentary assessment approach to the evaluation of traits.

This study investigated the extent to which momentary reports of coping are a traitlike phenomenon and the validity of a questionnaire assessment of coping style. Participants (N = 96) completed the questionnaire, then monitored stressful events and coping activities for 2 days using a hand-held computer that administered a brief assessment every 40 min. Momentary reports exhibited a sizable traitlike component: Individual differences accounted for 42% of the variance for 2 coping items and 15-30% of the variance for 15 items. The questionnaire assessment of coping style was a poor predictor of average momentary coping; the coping style measure and the aggregated momentary measure of trait coping shared 23% of their variance for religion and 0-12% for the 16 other coping measures. Self-report assessments of trait coping are poor measures of the trait component of momentary coping and very poor predictors of coping in specific situations.
