Reversal Errors

Ambridge, Bidgood, and Thomas (2020) conducted an elicitation-production task in which children with and without (high-functioning) autism described animations following priming with passive sentences. The authors report that children with autism were more likely than IQ-matched children without autism to commit reversal errors, for instance describing a scene in which the character Wendy surprised the character Bob by saying Wendy was surprised by Bob. We set out to test whether this effect replicated in a new sample of children with and without (high-functioning) autism (N = 26), and present a cumulative analysis in which data from the original study and the replication were pooled (N = 56). The main effect reported by Ambridge et al. (2020) replicated: While children with and without autism produced a similar number of passive responses in general, the responses of children with autism were significantly more likely to include reversal errors. Despite age- appropriate knowledge of constituent order in passive syntax, thematic role assignment is impaired among some children with high-functioning autism.

Urban noise can interfere with avian communication through masking, but birds can reduce this interference by altering their vocalizations. Although several experimental studies indicate that birds can rapidly change their vocalizations in response to sudden increases in ambient noise, none have investigated whether this is a learned response that depends on previous exposure. Black-capped chickadees ( Poecile atricapillus ) change the frequency of their songs in response to both fluctuating traffic noise and experimental noise. We investigated whether these responses to fluctuating noise depend on familiarity with noise. We confirmed that males in noisy areas sang higher-frequency songs than those in quiet areas, but found that only males in already-noisy territories shifted songs upwards in immediate response to experimental noise. Unexpectedly, males in more quiet territories shifted songs downwards in response to experimental noise. These results suggest that chickadees may require prior experience with fluctuating noise to adjust vocalizations in such a way as to minimize masking. Thus, learning to cope may be an important part of adjusting to acoustic life in the city.

Objective: ADHD persists in up to 60% into adulthood, and the reasons for persistence are not fully understood. The objective of this study was to characterize the neurofunctional basis of decision making in those with a childhood diagnosis of ADHD with either persistent or remitted symptoms in adulthood versus healthy control participants. Method: Thirty-two adults diagnosed with ADHD as children were split into persistent ( n = 18) or remitted ( n = 14) ADHD groups. Their neural activity and neurofunctional connectivity during a probabilistic reversal learning task were compared with 32 healthy controls. Results: Remitters showed significantly higher neural connectivity in final reversal error and probabilistic error conditions, and persisters depict higher neural connectivity in reversal errors than controls at a family-wise error (FWE) corrected whole-brain corrected threshold. Conclusion: Remitters may have utilized higher neural connectivity than controls to make successful decisions. Also, remitters may have utilized compensatory strategies to override any potential underlying ADHD deficits.
