Numerous studies have identified abnormal gaze in individuals with autism. However, only some findings have been replicated, the magnitude of effects is unclear, and the pattern of gaze differences ...across stimuli remains poorly understood. To address these gaps, a comprehensive meta-analysis of autism eye-tracking studies was conducted.
PubMed and a manual search of 1,132 publications were used to identify studies comparing looking behavior to social and/or nonsocial stimuli between individuals with autism and controls. Sample characteristics, eye-tracking methods, stimulus features, and regions of interest (ROIs) were coded for each comparison within each study. Multivariate mixed-effects meta-regression analyses examined the impact of study methodology, stimulus features, and ROI on effect sizes derived from comparisons using gaze-fixation metrics.
The search yielded 122 independent studies with 1,155 comparisons. Estimated effect sizes tended to be small to medium but varied substantially across stimuli and ROIs. Overall, nonsocial ROIs yielded larger effect sizes than social ROIs; however, eye and whole-face regions from stimuli with human interaction produced the largest effects (Hedges g = 0.47 and 0.50, respectively). Studies with weaker study designs or reporting yielded larger effects, but key effects remained significant and medium in size, even for high-rigor designs.
Individuals with autism show a reliable pattern of gaze abnormalities that suggests a basic problem with selecting socially relevant versus irrelevant information for attention and that persists across ages and worsens during perception of human interactions. Aggregation of gaze abnormalities across stimuli and ROIs could yield clinically useful risk assessment and quantitative, objective outcome measurements.
According to the facial feedback hypothesis, people's affective responses can be influenced by their own facial expression (e.g., smiling, pouting), even when their expression did not result from ...their emotional experiences. For example, Strack, Martin, and Stepper (1988) instructed participants to rate the funniness of cartoons using a pen that they held in their mouth. In line with the facial feedback hypothesis, when participants held the pen with their teeth (inducing a "smile"), they rated the cartoons as funnier than when they held the pen with their lips (inducing a "pout"). This seminal study of the facial feedback hypothesis has not been replicated directly. This Registered Replication Report describes the results of 17 independent direct replications of Study 1 from Strack et al. (1988), all of which followed the same vetted protocol. A meta-analysis of these studies examined the difference in funniness ratings between the "smile" and "pout" conditions. The original Strack et al. (1988) study reported a rating difference of 0.82 units on a 10-point Likert scale. Our meta-analysis revealed a rating difference of 0.03 units with a 95% confidence interval ranging from −0.11 to 0.16.
We used computer mouse tracking to investigate gender ratings of musical instruments in monolingual Spanish and English speakers. Musical instruments are tied to conceptual representations of gender. ...Consistent with previous research, English speakers rated the instruments male and female following these relatively stable conceptual representations, while Spanish speakers used grammar—in addition to their conceptual representations of gender—to perform their ratings. Interestingly, the responses of the Spanish speakers were influenced first by the grammatical information and 60 ms later by the conceptual representations. Measuring how participants' responses unfold over time provides novel information regarding the timing of grammatical gender.
Nine postdoctoral-level experienced psychodynamic supervisors were interviewed about working with a supervisee on a case involving parallel process (PP) that started in therapy and was enacted in ...supervision. Consensual qualitative research was used to analyze transcripts of the interviews. The general pattern that emerged from the analysis of the supervisors' reports was that clients behaved unusually in session, therapists "got hooked" by this change, therapists enacted the client's behavior in supervision, supervisors "got hooked," supervisors reflected on their reactions and intervened in a different way; reported outcomes were mostly positive (e.g., enhanced growth or understanding for the therapist). Results of this qualitative investigation provide evidence of PP and clues as to how experienced supervisors observe, describe, and respond to PP in ways that promote growth, insight, and understanding for their supervisees.
Clinical Impact Statement
Question: How do experienced psychodynamic supervisors identify and respond to parallel process (PP) in clinical supervision? Findings: We found evidence for an eight-step PP pattern that occurred across clients, therapists, and supervisors. Typically, a trigger set off the event, and generally, clients behaved unusually in session, therapists "got hooked" by this change and enacted the clients' behavior in supervision, supervisors "got hooked" and then reflected on their reactions and intervened, which led to positive and neutral outcomes. Meaning: Recognition of the steps can help supervisors and supervisees get unhooked from PP so that they can be more effective in supervision and psychotherapy. Next Steps: Results inform the development of better research questions about the emotional and behavioral patterns that flow up and down the supervisory triad.

To correct problems identified in existing measures of meaning in life (MIL) (lack of inclusion of items related to felt sense, mattering, and reflectivity), a new 8-item Meaning in Life Measure ...(MILM) was developed. Two subscales emerged: Experience (MILM-E, with items related to felt sense, mattering, goals, coherence) and Reflectivity (MILM-R, with items related to valuing thinking about meaning). High internal consistency and test-retest reliability were found for both subscales. Concurrent validity was demonstrated by a strong positive correlation between MILM-E and the Meaning in Life Questionnaire-Presence (MLQ-P), and a moderate correlation between MILM-R and the Meaning in Life Questionnaire-Search (MLQ-S). For both subscales, small to moderate positive correlations were found with subjective well-being, extraversion, conscientiousness, openness, agreeableness, self-deception, and impression management; moderate negative correlations were found with depression and emotional instability. Participants who were older, female, of higher income, and married with children scored slightly higher than their counterparts on MILM-E; women scored slightly higher than men on MILM-R. We concluded that the MILM has good psychometric properties and that MIL seems to be composed of two factors.
The statistical characteristics of the intensity of VLF-LF radio signals transmitted from the midlatitude radio stations and recorded by the receiver at the Mikhnevo geophysical observatory (54.94°N, ...37.73°E; Institute of Geosphere Dynamics, Russian Academy of Sciences) in 2007–2010 are analyzed. The experiments revealed strong variations in the intensity of radio signals during the deep solar minimum conditions, when the medium does not experience impacts from above associated with solar and geomagnetic activity. We relate the observed variations to the disturbances from below, which are caused by the meteorological and wave processes occurring in the lower atmosphere.
Variations in the geomagnetic and electric fields and variations of the total electron content (TEC) of the ionosphere recorded in the Baikal Rift Zone (BRZ) during the expeditions in 2009 and 2010 ...are analyzed. Synchronous bursts in the geomagnetic field on the ground and in the ionosphere, which are caused by propagation of electromagnetic disturbances (spherics) generated by the remote lightning discharges, are revealed. The analysis of the occurrence frequency of the electromagnetic disturbances at an altitude of ∼700 km shows that there is a preferred region of predominant propagation of these disturbances from the Earth-ionosphere waveguide to the upper ionosphere. When the ionospheric penetration point moves through this preferred region, the frequency spectrum of TEC variations changes, and the northern boundary of the region of spectral alteration is located at ∼54°N. The bursts in TEC that map on the zones of the main faults in the Tunka valley are identified. The results probably suggest a relation between the electromagnetic phenomena in the ionosphere and the structures in the lithosphere.
Initial results from the Active Plasma EXperiment North Star experiment are presented. The North Star active experiment included two separate plasma jet injections, both perpendicular to the Earth's ...magnetic field. The objective of the experiment is to investigate the interaction of high-speed (7–40 km/s) plasma jets with the ionospheric plasma and the coupling to the magnetosphere and lower ionosphere. The plasma jets were produced using an Explosive Type Generator device. This device is a shaped-charge device that vaporizes porous aluminum inside the generator and forces the vaporized products out of a nozzle, resulting in the production of a high-speed, partially ionized aluminum plasma jet. Instrumentation on three different payloads was used to obtain multi-point observations of the plasma jet properties, optical radiation from the jets, and ionospheric perturbations. Imagery, high-speed photometry, and spectrographic imagery using ground- and space-based sensors were used to monitor the dynamics and spectral content of the plasma jet. This paper describes the experiment and summarizes the initial results from the North Star experiment.
The purpose of the Fluxus‐1 and ‐2 active experiments is to study plasma jets injected parallel to the magnetic field and to study the interaction of these jets with the magnetic field. The ...experiments were conducted using a shaped‐charge device, known as an explosive type generator (ETG), that produced an artificial aluminum plasma jet. In Fluxus‐1 and ‐2 the jet was injected nearly parallel to the geomagnetic field at an altitude of 140 km toward an instrumented diagnostic payload located about 100 m away from the ETG. A ∼50% reduction in the magnetic field was observed as the plasma jet passed by the diagnostic payload. Comparisons of 3‐dimensional simulation results with the observed magnetic field perturbations suggest that the Fluxus‐1 plasma jet was ∼30° from the magnetic field direction while the Fluxus‐2 plasma jet was directed nearly parallel to the magnetic field.
