The Confusion of Fear and Surprise: A Developmental Study of the Perceptual-Attentional Limitation Hypothesis Using Eye Movements

The goal of the present study was to test the Perceptual-Attentional Limitation Hypothesis in children and adults by manipulating the distinctiveness between expressions and recording eye movements. Children 3–5 and 9–11 years old as well as adults were presented pairs of expressions and required to identify a target emotion. Children 3–5 years old were less accurate than those 9–11 years old and adults. All children viewed pictures longer than adults but did not spend more time attending to the relevant cues. For all participants, accuracy for the recognition of fear was lower than for surprise when the distinctive cue was in the brow only. They also took longer and spent more time in both the mouth and brow zones than when a cue was in the mouth or both areas. Adults and children 9–11 years old made more comparisons between the expressions when fear comprised a single distinctive cue in the brow than when the distinctive cue was in the mouth only or when both cues were present. Children 3–5 years old made more comparisons for brow only than both. The results of the present study extend on the Perceptual-Attentional Limitation Hypothesis showing an importance of both decoder and stimuli, and an interaction between decoder and stimuli characteristics.

Effects of a CARO on Stimulus Equivalence Formation: A Systematic Replication

The Psychological Record - In two experiments, we examined the disruptive effects of a “can’t answer” response option (CARO) on equivalence formation. The first experiment was a...     

The arousal model of moral condemnation

Previous research regarding the affective correlates of moral judgment has emphasized that this relation is rooted in the natural properties of discrete emotions, suggesting that specific emotions (e.g., disgust) increase moral condemnations for specific categories of moral violation (e.g. purity violations). In three experiments, we find that arousal increases the severity of moral condemnations, while emotion specificity effects remain absent. Results are compatible with constructivist approaches to emotion and the feelings as information account of social judgment.     

A New Perspective Concerning Experiments on Semantic Intuitions

Machery, Mallon, Nichols, and Stich [2004; forthcoming] use experimental methods to raise a spectre of doubt about reliance on intuitions in developing theories of reference which are then deployed in philosophical arguments outside the philosophy of language. Machery et al. ran a cross-cultural survey asking Western and East Asian participants about a famous case from the philosophical literature on reference (Kripke's Gödel example). They interpret their results as indicating that there is significant variation in participants' intuitions about semantic reference for that case. We argue that this interpretation is mistaken. We detail a type of ambiguity found in Machery et al.'s probe but not yet noted in the response literature. We argue that this epistemic ambiguity could have affected their results. We do not stop there, however: Rather than rest content with a possibility claim, we ran four studies to test the impact of this ambiguity on participants' responses. We found that this accounts for much of the variation in Machery et al.'s original experiment. We conclude that in the light of our new data, their argument is no longer convincing.     

A Developmental Vocabulary Assessment for Parents (DVAP): Validating Parental Report of Vocabulary Size in 2- to 7-Year-Old Children

Measuring individual differences in children's emerging language abilities is important to researchers and clinicians alike. The 2 most widely used methods for assessing children's vocabulary both have limitations: Experimenter-administered tests are time-consuming and expensive, and parent questionnaires have only been designed for children up to 37 months of age. Here, we test the validity of a new assessment to fill this gap: the Developmental Vocabulary Assessment for Parents (DVAP). In 4 experiments, we assess the reliability of this measure and its concurrent and predictive validity in samples of 2- to 7-year-old children. We found that the DVAP provides a rapid, cost-effective alternative to experimenter-administered vocabulary tests for children.     

The rise of mindfulness and its resonance with the Islamic tradition

Mindfulness-based interventions have grown in prominence over the past decade. Evidence of their efficacy has been an important driver of their widespread acceptance and proliferation. Although secularised, these mindfulness-based interventions are derived from and influenced by Eastern spiritual traditions, particularly Buddhism. For this reason, there is a need to explore the acceptability of such approaches among individuals firmly committed to theistic traditions such as Judaism, Christianity and Islam. This article examines the rise of mindfulness-based interventions, exploring the sparse literature concerning the acceptability of such approaches among individuals with theistic perspectives divergent from both secular worldviews and Buddhist narratives. Finally, the article proposes several bridging concepts that might help practitioners of mindfulness-based approaches communicate key aspects of these interventions in a manner more culturally attuned and religiously resonant with the worldviews of Muslim clients.     

Positive reappraisals after an offense: Event-related potentials and emotional effects of benefit-finding and compassion*

Using a within-subjects design, three emotion regulation strategies (compassion-focused reappraisal, benefit-focused reappraisal, and offense rumination) were tested for their effects on forgiveness, well-being, and event-related potentials. Participants (N = 37) recalled a recent interpersonal offense as the context for each emotion regulation strategy. Both decisional and emotional forgiveness increased significantly for the two reappraisal strategies compared to offense rumination. Compassion-focused reappraisal prompted the greatest increase in both decisional and emotional forgiveness. Furthermore, both reappraisal strategies increased positively oriented well-being measures (e.g. joy, gratitude) compared to offense rumination, with compassion-focused reappraisal demonstrating the largest effect on empathy. Late positive potential (LPP) amplitudes in response to unpleasant affect words were larger following the benefit-focused reappraisal strategy, indicating frontal LPP augmentation due to affective incongruence of the unpleasant stimuli with the positive, silver-lining orientation of the benefit-focused reappraisal emotion regulation strategy.     

The Efficacy of Cognitive Intervention in Mild Cognitive Impairment (MCI): a Meta-Analysis of Outcomes on Neuropsychological Measures

Cognitive training in MCI may stimulate pre-existing neural reserves or recruit neural circuitry as “compensatory scaffolding” prompting neuroplastic reorganization to meet task demands (Reuter-Lorenz & Park, 2014). However, existing systematic reviews and meta-analytic studies exploring the benefits of cognitive interventions in MCI have been mixed. An updated examination regarding the efficacy of cognitive intervention in MCI is needed given improvements in adherence to MCI diagnostic criteria in subject selection, better defined interventions and strategies applied, increased use of neuropsychological measures pre- and post-intervention, as well as identification of moderator variables which may influence treatment. As such, this meta-analytic review was conducted to examine the efficacy of cognitive intervention in individuals diagnosed with mild cognitive impairment (MCI) versus MCI controls based on performance of neuropsychological outcome measures in randomized controlled trials (RCT). RCT studies published from January 1995 to June 2017 were obtained through source databases of MEDLINE-R, PubMed, Healthstar, Global Health, PSYCH-INFO, and Health and Psychological Instruments using search parameters for MCI diagnostic category (mild cognitive impairment, MCI, pre-Alzheimer’s disease, early cognitive decline, early onset Alzheimer’s disease, and preclinical Alzheimer’s disease) and the intervention or training conducted (intervention, training, stimulation, rehabilitation, or treatment). Other inclusion and exclusion criteria included subject selection based on established MCI criteria, RCT design in an outpatient setting, MCI controls (active or passive), and outcomes based on objective neuropsychological measures. From the 1199 abstracts identified, 26 articles met inclusion criteria for the meta-analyses completed across eleven (11) countries; 92.31% of which have been published within the past 7 years. A series of meta-analyses were performed to examine the effects of cognitive intervention by cognitive domain, type of training, and intervention content (cognitive domain targeted). We found significant, moderate effects for multicomponent training (Hedges’ g observed?=?0.398; CI [0.164, 0.631]; Z?=?3.337; p?=?0.001; Q?=?55.511; df?=?15; p?=?0.000; I ² ?=?72.978%; τ ² ?=?0.146) as well as multidomain-focused strategies (Hedges’ g?=?0.230; 95% CI [0.108, 0.352]; Z?=?3.692; p??< 0.001; Q?=?12.713; df?=?12; p?=?0.390; I ² ?=?5.612; τ ² ?=?0.003). The effects for other interventions explored by cognitive domain, training type, or intervention content were indeterminate due to concerns for heterogeneity, bias, and small cell sizes. In addition, subgroup and meta-regression analyses were conducted with the moderators of MCI category, mode of intervention, training type, intervention content, program duration (total hours), type of control group (active or passive), post-intervention follow-up assessment period, and control for repeat administration. We found significant overall effects for intervention content with memory focused interventions appearing to be more effective than multidomain approaches. There was no evidence of an influence on outcomes for the other covariates examined. Overall, these findings suggest individuals with MCI who received multicomponent training or interventions targeting multiple domains (including lifestyle changes) were apt to display an improvement on outcome measures of cognition post-intervention. As such, multicomponent and multidomain forms of intervention may prompt recruitment of alternate neural processes as well as support primary networks to meet task demands simultaneously. In addition, interventions with memory and multidomain forms of content appear to be particularly helpful, with memory-based approaches possibly being more effective than multidomain methods. Other factors, such as program duration, appear to have less of an influence on intervention outcomes. Given this, although the creation of new primary network paths appears strained in MCI, interventions with memory-based or multidomain forms of content may facilitate partial activation of compensatory scaffolding and neuroplastic reorganization. The positive benefit of memory-based strategies may also reflect transfer effects indicative of compensatory network activation and the multiple-pathways involved in memory processes. Limitations of this review are similar to other meta-analysis in MCI, including a modest number studies, small sample sizes, multiple forms of interventions and types of training applied (some overlapping), and, while greatly improved in our view, a large diversity of instruments used to measure outcome. This is apt to have contributed to the presence of heterogeneity and publication bias precluding a more definitive determination of the outcomes observed.
