The link between suggestibility, compliance, and false confessions: A review using experimental and field studies

Psychometric properties of the Chinese version of the Gudjonsson compliance scale: scale validation and associations with mental health

BACKGROUND

Trait compliance involves people reacting favorably to demands made by others across different situations. This may lead to susceptibility to external pressures, exploitation, and manipulation. Moreover, trait compliance was found to correlate with various mental health outcomes, such as depression and anxiety. The Gudjonsson Compliance Scale (GCS) is an efficient tool for assessing trait compliance in Western contexts. To date, no study has validated the psychometric properties of the GCS in Chinese populations.

METHODS

Two college student samples from China were recruited. The first sample (N = 4,276) was used to conduct exploratory factor analysis. The second (N = 4,356) was used to perform a confirmatory factor analysis. The reliability, measurement invariance, and correlational tests were conducted on the two combined samples.

RESULTS

The Chinese GCS showed a 3-factor structure, with two items deleted. Reliability was supported by moderate-to-good internal consistency of the three-factor scales and good internal consistency on the full scale. Strong measurement invariance across sex, ethnicity, and group recruitment was supported. Scores of the total scale and factor scales were found to significantly associated with several mental health problems.

CONCLUSIONS

The Chinese version of the GCS appears to be a valid and reliable instrument for measuring trait compliance and could promote both the assessment and research on compliance in Chinese population.

Normative developmental vs. reverse developmental trends in memory distortion: a framework to investigate the impact of internal and external influences on memory and their relevance to legal decisions

There are two opposing positions regarding the development of memory: the normative developmental position, and the reverse developmental position. The normative position, which has long been the default presupposition, supports the notion that susceptibility to memory distortion, including false memories, decreases with age. In contrast, the concept of "developmental reversals" supports the notion that susceptibility to memory distortion and false memories increases with age. Each perspective finds support from existing theories as well as from research on endogenous and exogenous sources of influence. In a legal context, having an accurate understanding of the developmental course of false memory can contribute on the one hand to mitigating wrongful convictions and, on the other hand, to appreciating the accuracy of children's statements when warranted. This review aims to integrate the existing literature regarding these seemingly opposite developmental courses and construct a framework outlining the conditions under which we may observe one age trend over the other. This entails an examination of the paradigms that have been invoked to support these competing positions, specifically developmental responses to internal vs. external sources of distortion.

Paranormal experiences, sensory-processing sensitivity, and the priming of pareidolia

This investigation tested the effect of priming on pareidolia (the hearing of illusory words in ambiguous stimuli). Participants (41 women, 20 men, mean age 29.95 years) were assigned to primed (n = 30) or unprimed (n = 31) groups: the former were told the study was of ‘purported ghosts voices’, the latter ‘voices in noisy environments.’ Participants were assessed for perception of human voices within recordings of purported electronic voice phenomena (EVP), degraded human speech, normal human speech, and white noise. The primed group had significantly higher perception of voices within EVPs than in degraded speech, this difference was not found for unprimed participants. In contrast to the previous use of this design, the primed group did not have higher perception of voices in EVPs and degraded speech than did the unprimed group. The Aesthetic Sensitivity dimension of the Highly Sensitive Person Scale (HSPS) was associated with detection of degraded stimuli, but not with accuracy of stimulus identification. HSPS score was related to lifetime reporting of anomalous and paranormal experiences. This study partially replicates a paranormal priming effect and shows relationships between HSPS and detection of ambiguous stimuli and anomalous and paranormal experiences.

Suggested false memories of a non-existent film: forensically relevant individual differences in the crashing memories paradigm

There is ample evidence to suggest that posing leading questions is dangerous, in that it may elicit compliant responses that are not necessarily accurate. Further, suggestive questioning is considered to possibly result in the development of false memories, implied in the suggestion. [Crombag, H. F. M., Wagenaar, W. A., & van Koppen, P. J. (1996). Crashing memories and the problem of 'source monitoring'. Applied Cognitive Psychology, 10(2), 95-104. https://doi.org/10.1002/(SICI)1099-0720(199604)10:2<95::AID-ACP366>3.0.CO;2-#] introduced a crashing memories paradigm in which participants are asked a single leading question about a non-existent film. The present research sought to replicate the false-memory-eliciting effect of the crashing memory induction. Further, we sought to explore associations with forensically relevant personality traits, particularly acquiescence, compliance, and suggestibility. In two studies, a significant minority of participants endorsed the leading question about the non-existent film (25.7%, and 38% respectively). We found no support for an association with acquiescence or compliance, but suggestibility was associated with the development of false memories.
