Making sense out of uncertainty: cognitive strategies in the child custody decision-making process.

Child custody cases post-parental separation entail inherent complexities and uncertainties for legal experts and decision-makers, and are influenced by context factors. This study sheds light on how legal actors (i.e.

Parental experiences of the impact of grooming and criminal exploitation of children for county lines drug trafficking.

Background: County lines is used to describe the illicit drug supply model whereby drugs are transported from one area of the country to another, often by children believed to have been physically and psychologically coerced to do so. County lines is a serious threat to public health, with significant negative impacts on the physical and psychological health and wellbeing of children and families.

Methods: We conducted in-depth interviews with parents of children involved in county lines to understand their experiences and the impact of grooming and recruitment.

Sorting Insiders From Co-Workers: Remote Synchronous Computer-Mediated Triage for Investigating Insider Attacks.

Objective: Develop and investigate the potential of a remote, computer-mediated and synchronous text-based triage, which we refer to as for quickly highlighting persons of interest after an insider attack.

Background: Insiders maliciously exploit legitimate access to impair the confidentiality and integrity of organizations. The globalisation of organisations and advancement of information technology means employees are often dispersed across national and international sites, working around the clock, often remotely.

Noncoercive human intelligence gathering.

Despite widespread recognition that coercive methods for intelligence gathering are unethical and counterproductive, there is an absence of empirical evidence for effective alternatives. We compared 2 noncoercive methods-the Modified Cognitive Interview (MCI) and Controlled Cognitive Engagement (CCE)-adapted for intelligence gathering by adding a moral frame to encourage interviewees to consciously consider sharing intelligence. Participants from the general population experienced an unexpected live event where equipment was damaged, and an argument ensued.

Unanticipated questions can yield unanticipated outcomes in investigative interviews.

Asking unanticipated questions in investigative interviews can elicit differences in the verbal behaviour of truth-tellers and liars: When faced with unanticipated questions, liars give less detailed and consistent responses than truth-tellers. Do such differences in verbal behaviour lead to an improvement in the accuracy of interviewers' veracity judgements? Two empirical studies evaluated the efficacy of the unanticipated questions technique. Experiment 1 compared two types of unanticipated questions (questions regarding the planning of a task and questions regarding the specific spatial and temporal details associated with the task), assessing the veracity judgements of interviewers and verbal content of interviewees' responses.

Drawing the answers: Sketching to support free and probed recall by child witnesses and victims with autism spectrum disorder.

The success of witness interviews in the criminal justice system depends on the accuracy of information obtained, which is a function of both amount and quality of information. Attempts to enhance witness retrieval such as mental reinstatement of context have been designed with typically developed adults in mind. In this article, the relative benefits of mental and sketch reinstatement mnemonics are explored with both typically developing children and children with autism.

No Evidence Against Sketch Reinstatement of Context, Verbal Labels or the Use of Registered Intermediaries for Children with Autism Spectrum Disorder: Response to Henry et al. (2017).

Recently, Henry et al. (J Autism Dev Disord 8:2348-2362, 2017) found no evidence for the use of Verbal Labels, Sketch Reinstatement of Context and Registered Intermediaries by forensic practitioners when interviewing children with a diagnosis of autism spectrum disorder. We consider their claims, noting the limited ecological validity of the experimental paradigm, the impacts of repeated interviewing where retrieval support is not provided at first retrieval, question the interviewer/intermediary training and their population relevant experience, and comment on the suppression of population variances.

Enabling spontaneous analogy through heuristic change.

Despite analogy playing a central role in theories of problem solving, learning and education, demonstrations of spontaneous analogical transfer are rare. Here, we present a theory of heuristic change for spontaneous analogical transfer, tested in four experiments that manipulated the experience of failure to solve a source problem prior to attempting a target problem. In Experiment 1, participants solved more source problems that contained an additional financial constraint designed to signal the inappropriateness of moves that maximized progress towards the goal.

Analyzing Decision Logs to Understand Decision Making in Serious Crime Investigations.

Objective To study decision making by detectives when investigating serious crime through the examination of decision logs to explore hypothesis generation and evidence selection. Background Decision logs are used to record and justify decisions made during serious crime investigations. The complexity of investigative decision making is well documented, as are the errors associated with miscarriages of justice and inquests.

Sleep promotes analogical transfer in problem solving.

Analogical problem solving requires using a known solution from one problem to apply to a related problem. Sleep is known to have profound effects on memory and information restructuring, and so we tested whether sleep promoted such analogical transfer, determining whether improvement was due to subjective memory for problems, subjective recognition of similarity across related problems, or by abstract generalisation of structure. In Experiment 1, participants were exposed to a set of source problems.

Sketching to remember: episodic free recall task support for child witnesses and victims with autism spectrum disorder.

Deficits in episodic free-recall memory performance have been reported in children with autism spectrum disorder (ASD), yet best practice dictates that child witness/victim interviews commence with a free-recall account. No 'tools' exist to support children with ASD to freely recall episodic information. Here, the efficacy of a novel retrieval technique, Sketch reinstatement of context (Sketch-RC), is compared with mental reinstatement of context and a no support control.

Finding a needle in a haystack: toward a psychologically informed method for aviation security screening.

Current aviation security systems identify behavioral indicators of deception to assess risks to flights, but they lack a strong psychological basis or empirical validation. We present a new method that tests the veracity of passenger accounts. In an in vivo double-blind randomized-control trial conducted in international airports, security agents detected 66% of deceptive passengers using the veracity test method compared with less than 5% using behavioral indicator recognition.

Detecting insider threats through language change.

The act of conducting an insider attack carries with it cognitive and social challenges that may affect an offender's day-to-day work behavior. We test this hypothesis by examining the language used in e-mails that were sent as part of a 6-hr workplace simulation. The simulation involved participants (N = 54) examining databases and exchanging information as part of a four-stage organized crime investigation.

Act first, think later: the presence and absence of inferential planning in problem solving.

Planning is fundamental to successful problem solving, yet individuals sometimes fail to plan even one step ahead when it lies within their competence to do so. In this article, we report two experiments in which we explored variants of a ball-weighing puzzle, a problem that has only two steps, yet nonetheless yields performance consistent with a failure to plan. The results fit a computational model in which a solver's attempts are determined by two heuristics: maximization of the apparent progress made toward the problem goal and minimization of the problem space in which attempts are sought.

When help becomes hindrance: unexpected errors of omission and commission in eyewitness memory resulting from change temporal order at retrieval?

An experimental mock eyewitness study is reported that compared Free and reverse order recall of an empirically informed scripted crime event. Proponents of reverse order recall suggest it facilitates recovery of script incidental information and increases the total amount of information recalled. However, compared with free recall it was found to impair overall retrieval performance, resulting in fewer script consistent events, reduced recall of correct information, increased confabulations, and lowered accuracy proportional to items retrieved.

Explaining away the negative effects of evaluation on analogical transfer: the perils of premature evaluation.

Four experiments explored effects on analogical transfer of evaluating solutions to base problems. In contrast to reports of positive effects of explanation, evaluation consistently reduced transfer rates and impaired mental representations of base material. This effect was not ameliorated by encoding for a later memory test, summarizing, or engaging in similar processes at encoding and recall.

Does incubation enhance problem solving? A meta-analytic review.

A meta-analytic review of empirical studies that have investigated incubation effects on problem solving is reported. Although some researchers have reported increased solution rates after an incubation period (i.e.

Analogue versus propositional representation in congenitally blind individuals.

Congenitally blind individuals are generally less accurate at mentally manipulating objects than sighted people. However, they often score higher on tests of short- and long-term verbal memory, and it has been suggested that an enhanced propositional representation compensates for inefficiencies in analogue visuospatial representation. Here, congenitally blind, blindfolded, and sighted participants recalled descriptions of relative object locations.

It looks easy! Heuristics for combinatorial optimization problems.

Human performance on instances of computationally intractable optimization problems, such as the travelling salesperson problem (TSP), can be excellent. We have proposed a boundary-following heuristic to account for this finding. We report three experiments with TSPs where the capacity to employ this heuristic was varied.

Convex hull or crossing avoidance? Solution heuristics in the traveling salesperson problem.

Untrained adults appear to have access to cognitive processes that allow them to perform well in the Euclidean version of the traveling salesperson problem (E-TSP). They do so despite the famous computational intractability of the problem, which stems from its combinatorial complexity. A current hypothesis is the humans' good performance is based on following a strategy of connecting boundary points in order (the convex hull hypothesis).

What makes an insight problem? The roles of heuristics, goal conception, and solution recoding in knowledge-lean problems.

Four experiments investigated transformation problems with insight characteristics. In Experiment 1, performance on a version of the 6-coin problem that had a concrete and visualizable solution followed a hill-climbing heuristic. Experiment 2 demonstrated that the difficulty of a version of the problem that potentially required insight for solution stems from the same hill-climbing heuristic, which creates an implicit conceptual block.

On the generation and evaluation of inferences from single premises.

A theory of how individuals construct mental models to draw inferences from single premises was tested in three experiments. Experiment 1 confirmed a counterintuitive prediction that it is easier to generate inferences between conditionals and disjunctions than it is to evaluate them. Experiment 2 replicated this finding, but an advantage found in the first experiment for conditional-to-disjunction over disjunction-to-conditional inferences was removed with different sentence contents.

Dynamics and constraints in insight problem solving.

This article reports 2 experiments that investigated performance on a novel insight problem, the 8-coin problem. The authors hypothesized that participants would make certain initial moves (strategic moves) that seemed to make progress according to the problem instructions but that nonetheless would guarantee failure to solve the problem. Experiment 1 manipulated the starting state of the problem and showed that overall solution rates were lower when such strategic moves were available.
