Perceiving gaze from head and eye rotations: An integrative challenge for children and adults

Gaze is an emergent visual feature. A person's gaze direction is perceived not just based on the rotation of their eyes, but also their head. At least among adults, this integrative process appears to be flexible such that one feature can be weighted more heavily than the other depending on the circumstances. Yet it is unclear how this weighting might vary across individuals or across development. When children engage emergent gaze, do they prioritize cues from the head and eyes similarly to adults? Is the perception of gaze among individuals with autism spectrum disorder (ASD) emergent, or is it reliant on a single feature? Sixty adults (M = 29.86 years‐of‐age), thirty‐seven typically developing children and adolescents (M = 9.3 years‐of‐age; range = 7–15), and eighteen children with ASD (M = 9.72 years‐of‐age; range = 7–15) viewed faces with leftward, rightward, or direct head rotations in conjunction with leftward or rightward pupil rotations, and then indicated whether the face was looking leftward or rightward. All individuals, across development and ASD status, used head rotation to infer gaze direction, albeit with some individual differences. However, the use of pupil rotation was heavily dependent on age. Finally, children with ASD used pupil rotation significantly less than typically developing (TD) children when inferring gaze direction, even after accounting for age. Our approach provides a novel framework for understanding individual and group differences in gaze as it is actually perceived—as an emergent feature. Furthermore, this study begins to address an important gap in ASD literature, taking the first look at emergent gaze perception in this population.     

Evolutionary roots of intuitive parenting: Maternal competence in chimpanzees

Intuitive parenting behaviours have been shown to be universal in humans and appear to be based on psychobiological preadaptedness. This study is an exploration of the evolutionary roots of intuitive parenting through naturalistic observation of mother chimpanzees' interaction with their very young infants. Maternal competence is demonstrated initially through the behaviours of carrying the newborn infant and allowing the infant to nurse. Very early mother–infant interactions include play, ‘exercise’, cradling and grooming. Chimpanzee mothers also assess their offspring's behavioural state and muscle tone through visual inspections and movement of legs, arms, fingers and toes. Chimpanzee mothers and infants, as early as 2 weeks of age, spend some time in mutual gaze. Neonatal chimpanzees are capable of sustained face-to-face interactions, as these were observed in nursery-reared chimpanzee interactions with human adults; however, it appears that chimpanzee mothers encourage mutual gaze with their infants for only brief durations. Chimpanzees with good maternal competence exhibit sensitive responsivity to infants' communicatory signals. Thus the results of this study support the claim that there are evolutionary and comparative foundations of intuitive parenting evident in the maternal behaviour and maternal competence of chimpanzees.     

Gaze Patterns When Looking at Emotional Pictures: Motivationally Biased Attention

Pictures of either emotionally neutral, pleasant (affectionate), or unpleasant (threat and injury) scenes were paired with nonemotional control pictures and presented for 3 s, while eye fixations were monitored. Preferential attention to the emotional picture of eah pair occurred at an early processing stage: The probability of placement of the first fixation and the proportion of viewing time during the first 500 ms were higher for both pleasant and unpleasant pictures than for neutral pictures, whereas later fixation location and time were not differentially affected. This suggests that, when emotional and nonemotional stimuli are presented simultaneously, emotional meaning captures initial overt orienting and engages attention early, as measured by gaze direction and duration. The possibility that this effect could be accounted for by perceptual differences—such as luminance and complexity—between emotional and neutral pictures was ruled out.     

Allocation of speech in conversation

In a replication and extension of Conger and Killeen's (1974) widely cited demonstration of matching in conversations, we evaluated nine participants’ allocation of speech and gaze to two conversational partners. German speakers participated in two 90‐min sessions in which confederates uttered approval on independent variable‐interval schedules. In one of the sessions, confederates uttered approval contingent upon and contiguous with eye contact whereas in the other session approval was uttered independent of the participant's gaze. Several measures of participants’ verbal behavior were taken, including relative duration and rate of speech and gaze. These were compared to confederates’ relative rate of approval and relative duration and rate of talk. The generalized matching equation was fitted to the various relations between participants’ behavior and confederates’ behavior. Conger and Killeen's results were not replicated; participants’ response allocation did not show a systematic relation to the confederates’ relative rate of approval. The strongest relations were to overall talk, rather than approval. In both conditions, the participant talked more to the confederate who talked less—inverse or antimatching. Participants’ gaze showed the same inverse relation to the confederates’ talk. Requiring gaze to be directed toward a confederate for delivery of approval made no difference in the results. The absence of a difference combined with prior research suggests that matching or antimatching in conversations is more likely due to induction than to reinforcement.     

Working with and ‘seeing through’ the sexual transference in the psychotherapy of an adolescent boy

This paper explores the challenges and developmental opportunities of working with the sexual transference in psychotherapy with adolescents. Psychoanalytic contributions investigating the nature of adolescent sexuality and the developmental move from a narcissistic organisation to a capacity to form intimate relationships are reviewed, and the question of what happens when there is a lack of containment in infancy is addressed. The way in which unintegrated sexual impulses and phantasies can invade the therapeutic relationship is further discussed through the account of the weekly psychotherapy of a 16-year-old boy who formed a powerful sexual transference to his female therapist. The paper highlights how working through the sexual transference enabled this young man to face his developmental paralysis and begin to use the therapy as an opportunity for psychic growth.     

Genuine eye contact elicits self-referential processing

The effect of eye contact on self-awareness was investigated with implicit measures based on the use of first-person singular pronouns in sentences. The measures were proposed to tap into self-referential processing, that is, information processing associated with self-awareness. In addition, participants filled in a questionnaire measuring explicit self-awareness. In Experiment 1, the stimulus was a video clip showing another person and, in Experiment 2, the stimulus was a live person. In both experiments, participants were divided into two groups and presented with the stimulus person either making eye contact or gazing downward, depending on the group assignment. During the task, the gaze stimulus was presented before each trial of the pronoun-selection task. Eye contact was found to increase the use of first-person pronouns, but only when participants were facing a real person, not when they were looking at a video of a person. No difference in self-reported self-awareness was found between the two gaze direction groups in either experiment. The results indicate that eye contact elicits self-referential processing, but the effect may be stronger, or possibly limited to, live interaction.     

Are you looking my way? Ostracism widens the cone of gaze

Ostracized individuals demonstrate an increased need for belonging. To satisfy this need, they search for signals of inclusion, one of which may be another person’s gaze directed at oneself. We tested if ostracized, compared to included, individuals judge a greater degree of averted gaze as still being direct. This range of gaze angles still viewed as direct has been dubbed “the cone of (direct) gaze”. In the current research, ostracized and included participants viewed friendly-looking face stimuli with direct or slightly averted gaze (0°, 2°, 4°, 6°, and 8° to the left and to the right) and judged whether stimulus persons were looking at them or not. Ostracized individuals demonstrated a wider gaze cone than included individuals.     

Influence of emotional expression on the processing of gaze direction

Research demonstrates an influence of gaze direction in emotion recognition. Here we examined whether facial affect similarly influences recognition of gaze direction. Across two studies we found that averted relative to direct gaze was processed more quickly and accurately when coupled with fear, and direct relative to averted gaze with anger. Also evident was that slower overall gaze processing was associated with increased interaction effects between emotion and gaze. Examining individual differences, therefore, enabled us to extend previous research examining speed of processing as a moderator of the interaction effect, while holding constant task demands and stimulus features. Unexpectedly, a main effect emerged such that averted relative to direct gaze was found to be processed more quickly and accurately overall. This effect was not moderated by processing speed and is discussed as a potential stimulus-driven effect that may help explain discrepant findings in the literature.

Eye contact does not facilitate detection in children with autism

Eye contact is crucial in achieving social communication. Deviant patterns of eye contact behavior are found in individuals with autism, who suffer from severe social and communicative deficits. This study used a visual oddball paradigm to investigate whether children with high functioning autism have difficulty in detecting mutual gaze under experimental conditions. The results revealed that children with autism were no better at detecting direct gaze than at detecting averted gaze, which is unlike normal children. This suggests that whereas typically developing children have the ability to detect direct gaze, children with autism do not. This might result in altered eye-contact behavior, which hampers subsequent development of social and communicative skills.     

A longitudinal study of the development of shifts of gaze to a peripheral stimulus in preterm infants with transient periventricular echogenicity

Shifts of gaze to peripheral targets were studied longitudinally, between 6 and 26 weeks corrected age, in full-term and very preterm infants with transient periventricular echogenicity (PVE). Before 10 weeks, simple shifts of gaze were faster and more frequent in preterms with PVE<14 days than in full-terms, suggesting these preterms profited from additional early visual experience. After 16 weeks, there were subtle differences between full- and preterm infants in the development of shifts of gaze requiring disengagement. The differences suggest that, after disengagement had become established, its fine-tuning occurred more slowly in the preterms. Slower fine-tuning of disengagement was not associated with duration of PVE, since it was more marked in preterms with PVE<14 days than in preterms with PVE> or =14 days. The differences in performance between full- and preterm infants were small. However, even small differences may affect the efficiency of visually guided behaviors.
