Mind wandering during film comprehension: The role of prior knowledge and situational interest

This study assessed the occurrence and factors that influence mind wandering (MW) in the domain of film comprehension. The cascading model of inattention assumes that a stronger mental representation (i.e., a situation model) during comprehension results in less MW. Accordingly, a suppression hypothesis suggests that MW would decrease as a function of having the knowledge of the plot of a film prior to viewing, because the prior-knowledge would help to strengthen the situation model during comprehension. Furthermore, an interest-moderation hypothesis would predict that the suppression effect of prior-knowledge would only emerge when there was interest in viewing the film. In the current experiment, 108 participants either read a short story that depicted the plot (i.e., prior-knowledge condition) or read an unrelated story of equal length (control condition) prior to viewing the short film (32.5 minutes) entitled The Red Balloon. Participants self-reported their interest in viewing the film immediately before the film was presented. MW was tracked using a self-report method targeting instances of MW with metacognitive awareness. Participants in the prior-knowledge condition reported less MW compared with the control condition, thereby supporting the suppression hypothesis. MW also decreased over the duration of the film, but only for those with prior-knowledge of the film. Finally, prior-knowledge effects on MW were only observed when interest was average or high, but not when interest was low.

Politics, schadenfreude, and ingroup identification: The sometimes happy thing about a poor economy and death

Political campaigns are often characterized by the various events occurring that move the tide in favor of one candidate or another. Each event, depending on which candidate it favors or harms, produces either happiness or sadness for those who care about the outcome. This research examined whether such reactions would hold for events that are misfortunes for other people and even when they negatively affect society more broadly regardless of political party affiliation. Ingroup (i.e. political party) identification was examined as an important moderating variable. In four studies, undergraduate participants gave their emotional reactions to news articles describing misfortunes happening to others (e.g. poor economic news and house foreclosures). Party affiliation and the intensity of ingroup identification strongly predicted whether these events produced schadenfreude.     

Glutamate receptors in the medial geniculate nucleus are necessary for expression and extinction of conditioned fear in rats

Auditory fear conditioning requires anatomical projections from the medial geniculate nucleus (MGN) of the thalamus to the amygdala. Several lines of work indicate that the MGN is a critical sensory relay for auditory information during conditioning, but is not itself involved in the encoding of long-term fear memories. In the present experiments, we examined whether the MGN plays a similar role in the extinction of conditioned fear. Twenty-four hours after Pavlovian fear conditioning, rats received bilateral intra-thalamic infusions of either with NBQX (an AMPA receptor antagonist; Experiment 1) or MK-801 (an NMDA receptor antagonist; Experiment 1), anisomycin (a protein synthesis inhibitor; Experiment 2) or U0126 (a MEK inhibitor; Experiment 3) immediately prior to an extinction session in a novel context. The next day rats received a tone test in a drug-free state to assess their extinction memory; freezing served as an index of fear. Glutamate receptor antagonism prevented both the expression and extinction of conditioned fear. In contrast, neither anisomycin nor U0126 affected extinction. These results suggest that the MGN is a critical sensory relay for auditory information during extinction training, but is not itself a site of plasticity underlying the formation of the extinction memory.     

Genetic Counselors’ Perception of the Effect on Practice of Laws Restricting Abortion

In 2013, twenty-two states enacted seventy provisions restricting access to abortion. The legislation restricted access to abortions by instituting more regulations on providers and facilities, by prohibiting abortion prior to viability, by restricting funding available to patients and by requiring patients to wait a mandatory time period before having a procedure. Genetic counselors are trained to provide unbiased, comprehensive information in a non-directive style in order to allow patients to exercise their reproductive freedom. We developed a survey of 37 questions for genetic counselors to gauge the potential impact these provisions will have on their ability to be a patient advocate. A total of 286 individuals completed the survey; however, not all respondents answered all questions. Qualitative questions complemented quantitative survey entries, allowing respondents to input thoughts and examples. Results indicate genetic counselors in all regions share similar professional opinions about the provisions. More genetic counselors in the South and Midwest noticed changes impacting patients since the provisions have been enacted. These regional differences correlate with the location of states that have seem the greatest increase in antiabortion provisions.     

Collaborative communication efficiency is linked to relationship satisfaction in dating couples

The speed, or efficiency, in which people communicate is linked to positive interpersonal outcomes. However, no studies of communication efficiency have examined romantic partners, making it unclear whether efficient communication is linked to relationship satisfaction above and beyond previously identified communication skills (e.g., problem‐solving). We recruited dating couples (N = 56) to attend a laboratory session to complete survey measures and a collaborative communication task. Multilevel models demonstrated that both task efficiency (β = ?.36, p = .04) and self‐reported problem‐solving communication skills (β = .28, p = .002) were associated with relationship satisfaction. Results suggest that communication task efficiency can be meaningfully applied to the study of romantic relationships and couple communication skills.     

The Cognitive Demands of Gait Retraining in Runners: An EEG Study

Abstract

High impact forces during running have been associated with tibial stress injuries. Previous research has demonstrated increasing step rate will decrease impact forces during running. However, no research has determined the cognitive demand of gait retraining. The primary purpose was to determine the cognitive demand and effectiveness of field-based gait retraining. We hypothesized that in-field gait retraining would alter running mechanics without increasing cognitive workload as measured by EEG following learning. Runners with a history of tibial injury completed a gait retraining protocol which included a baseline run, retraining phase, practice phase, and re-assessment following retraining protocol. Results demonstrated an increase in the theta, beta, and gamma power within prefrontal cortex during new learning and corresponding return to baseline following skill acquisition and changes across alpha, beta, gamma, mu, and theta in the motor cortex (p < .05). In the midline superior parietal cortex, spectral power was greater for theta activity during new learning with a corresponding alpha suppression. Overall, the results demonstrated the use of EEG as an effective tool to measure cognitive demand for implicit motor learning and the effectiveness of in-field gait retraining.

TMS to the “occipital face area” affects recognition but not categorization of faces

The human cortical system for face perception is comprised of a network of connected regions including the middle fusiform gyrus (“fusiform face area” or FFA), the inferior occipital cortex (“occipital face area” or OFA), and the superior temporal sulcus. The traditional hierarchical feedforward model of visual processing suggests information flows from early visual cortex to the OFA for initial face feature analysis to higher order regions including the FFA for identity recognition. However, patient data suggest an alternative model. Patients with acquired prosopagnosia, an inability to visually recognize faces, have been documented with lesions to the OFA but who nevertheless show face-selective activation in the FFA. Moreover, their ability to categorize faces remains intact. This suggests that the FFA is not solely responsible for face recognition and the network is not strictly hierarchical, but may be organized in a reverse hierarchical fashion. We used transcranial magnetic stimulation (TMS) to temporarily disrupt processing in the OFA in neurologically-intact individuals and found participants’ ability to categorize intact versus scrambled faces was unaffected, however face identity discrimination was significantly impaired. This suggests that face categorization but not recognition can occur without the “earlier” OFA being online and indicates that “lower level” face category processing may be assumed by other intact face network regions such as the FFA. These results are consistent with the patient data and support a non-hierarchical, global-to-local model with re-entrant connections between the OFA and other face processing areas.
