Enhancing parental reflective functioning through early dyadic interventions: A systematic review and meta‐analysis

Parental reflective functioning (PRF) is an important predictor of infant attachment, and interventions that target parent–infant/toddler dyads who are experiencing significant problems have the potential to improve PRF. A range of dyadic interventions have been developed over the past two decades, some of which explicitly target PRF as part of their theory of change, and some that do not explicitly target PRF, but that have measured it as an outcome. However, no meta‐analytic review of the impact of these interventions has been carried out to date. The aim of this review was to evaluate the effectiveness of dyadic interventions targeting parents of infant and toddlers, in improving PRF and a number of secondary outcomes. A systematic review and meta‐analysis was conducted in which key electronic databases were searched up to October 2018. Eligible studies were identified and data extracted. Data were synthesised using meta‐analysis and expressed as both effect sizes and risk ratios. Six studies were identified providing a total of 521 participants. The results of six meta‐analyses showed a nonsignificant moderate improvement in PRF in the intervention group (standardised mean difference [SMD]: –0.46; 95% confidence interval [CI] [–0.97, 0.04]) and a significant reduction in disorganised attachment (risk ratio: 0.50; 95% CI [0.27, 0.90]). There was no evidence for intervention effects on attachment security (odds ratio: 0.71; 95% CI [0.19, 2.64]), parent–infant interaction (SMD: –0.10; 95% CI [–0.46, 0.26]), parental depression (SMD: –1.55; 95% CI [–3.74, 0.64]) or parental global distress (SMD: –0.19, 95% CI [–3.04, 22.65]). There were insufficient data to conduct subgroup analysis (i.e. to compare the effectiveness of mentalisation‐based treatment with non‐mentalization‐based treatment interventions). Relational early interventions may have important benefits in improving PRF and reducing the prevalence of attachment disorganisation. The implications for future research are discussed.     

Searching for two categories of target in dynamic visual displays impairs monitoring ability

Target onsets in dynamically changing displays can be predicted when contingencies exist between different stimulus states over time. In the present study, we examined predictive monitoring when participants searched dynamically changing displays of numbers and colored squares for a color target, a number target, or both. Stimuli were presented in both contiguous and discrete spatial configurations. Response time (RT) and accuracy were recorded, and evidence of predictive monitoring was assessed via first fixations and refixations of target‐predictive stimuli. RTs to target onsets and evidence of predictive monitoring were reduced in dual‐target, relative to single‐target, conditions. Further, predictive monitoring did not speed RTs but was influenced by display configuration. In particular, discrete displays impaired monitoring for number targets in the dual‐target condition. Implications exist for real‐world visual tasks involving multiple target categories and for visual display design.     

Adaptive Anchoring Model: How Static and Dynamic Presentations of Time Series Influence Judgments and Predictions

When attempting to predict future events, people commonly rely on historical data. One psychological characteristic of judgmental forecasting of time series, established by research, is that when people make forecasts from series, they tend to underestimate future values for upward trends and overestimate them for downward ones, so‐called trend‐damping (modeled by anchoring on, and insufficient adjustment from, the average of recent time series values). Events in a time series can be experienced sequentially (dynamic mode), or they can also be retrospectively viewed simultaneously (static mode), not experienced individually in real time. In one experiment, we studied the influence of presentation mode (dynamic and static) on two sorts of judgment: (a) predictions of the next event (forecast) and (b) estimation of the average value of all the events in the presented series (average estimation). Participants' responses in dynamic mode were anchored on more recent events than in static mode for all types of judgment but with different consequences; hence, dynamic presentation improved prediction accuracy, but not estimation. These results are not anticipated by existing theoretical accounts; we develop and present an agent‐based model—the adaptive anchoring model (ADAM)—to account for the difference between processing sequences of dynamically and statically presented stimuli (visually presented data). ADAM captures how variation in presentation mode produces variation in responses (and the accuracy of these responses) in both forecasting and judgment tasks. ADAM's model predictions for the forecasting and judgment tasks fit better with the response data than a linear‐regression time series model. Moreover, ADAM outperformed autoregressive‐integrated‐moving‐average (ARIMA) and exponential‐smoothing models, while neither of these models accounts for people's responses on the average estimation task.

Gorillas we have missed: sustained inattentional deafness for dynamic events

It is now well-known that the absence of attention can leave us 'blind' to visual stimuli that are very obvious under normal viewing conditions (e.g. a person dressed as a gorilla; Simons & Chabris, 1999). However, the question of whether hearing can ever be susceptible to such effects remains open. Here, we present evidence that the absence of attention can leave people 'deaf' to the presence of an 'auditory gorilla' which is audible for 19s and clearly noticeable under full attention. These findings provide the first ever demonstration of sustained inattentional deafness. The effect is all the more surprising because it occurs within a lifelike, three-dimensional auditory scene in which the unnoticed stimulus moves through the middle of several other dynamic auditory stimuli.     

What do memory data tell us about the role of contingency awareness in evaluative conditioning?

Evaluative conditioning (EC) refers to the effect that pairings of a conditioned stimulus (CS) with a valenced unconditioned stimulus (US) lead to changes in the evaluation of the CS. There have been recurring debates about whether EC requires awareness of the contingency between CSs and USs during learning. We argue that the memory performance data obtained in the standard paradigm remain ambiguous about the role of contingency awareness during the encoding of CS–US pairings. First, memory performance data are unable to distinguish between encoding-related versus retrieval-related effects. Second, the relation between memory performance and evaluation is correlational, which limits conclusions about causal relations between memory performance and EC effects. These ambiguities imply that any possible data pattern can be interpreted in at least two different ways. It is concluded that a resolution of the current debate requires alternative approaches in which contingency awareness is experimentally manipulated during the encoding of CS–US pairings.     

On the intentional control of conditioned evaluative responses

The evaluative conditioning (EC) effect is defined as a change in the evaluation of a conditioned stimulus (CS) due to its pairing with a valenced unconditioned stimulus (US). The current research investigated the controllability of EC effects by asking participants to either promote or prevent the influence of CS–US pairings before they provided evaluative ratings of the CS. Experiment 1 showed that instructions to maximize or minimize the influence of CS–US pairings moderated EC effects in line with task instructions. However, this moderation was observed only when participants were able to recall the valence of the US that had been paired with a given CS. When participants failed to remember the valence of the US, significant EC effects emerged regardless of control instructions. Experiment 2 tested whether the influence of CS–US pairings on CS evaluations can be intentionally reversed. The results showed that reversal instructions led to a reverse EC effect when participants were able to recall the valence of the US that had been paired with a given CS, but not when they were unable to recall the valence of the US. Taken together, these results suggest that US valence memory is a necessary precondition for controlling the expression of a conditioned evaluative response, but it is not a necessary precondition for the emergence of EC effects per se.     

Don't mind meat? The denial of mind to animals used for human consumption

Many people like eating meat, but most are reluctant to harm things that have minds. The current three studies show that this dissonance motivates people to deny minds to animals. Study 1 demonstrates that animals considered appropriate for human consumption are ascribed diminished mental capacities. Study 2 shows that meat eaters are motivated to deny minds to food animals when they are reminded of the link between meat and animal suffering. Finally, Study 3 provides direct support for our dissonance hypothesis, showing that expectations regarding the immediate consumption of meat increase mind denial. Moreover, this mind denial in turn reduces negative affect associated with dissonance. The findings highlight the role of dissonance reduction in facilitating the practice of meat eating and protecting cultural commitments.     

Using the dual-target cost to explore the nature of search target representations

Eye movements were monitored to examine search efficiency and infer how color is mentally represented to guide search for multiple targets. Observers located a single color target very efficiently by fixating colors similar to the target. However, simultaneous search for 2 colors produced a dual-target cost. In addition, as the similarity between the 2 target colors decreased, search efficiency suffered, resulting in more fixations on colors dissimilar to both target colors, which we describe as a "split-target cost." The patterns of fixations provide evidence to the type of mental representations guiding search. When the 2 targets are dissimilar, they are apparently encoded as separate and discrete representations. The fixation patterns for more similar targets can be explained with either 2 discrete target representations or a single, unitary range containing the target colors as well as the colors between them in color space.
