Second, as children got older, more trials consisted of only two runs, a pattern that has previously been interpreted as a difficulty with holding two target categories simultaneously in mind (Jóhannesson et al., 2016; Kristjánsson et al., 2014).
For each gene, we computed the geometric mean of the gene-profile p-values over the nine teams, which we interpreted as the difficulty level of each gene.
This result could also be interpreted as a difficulty in holding down the lever for SHR, relative to LE, due to a motor limitation or its lower body weight; it could also be interpreted as diminished motivation due to lower rates of reinforcement (in turn derived from inefficient responding).
Using midbrain or posterior cingulate cortex (PCC) seeds (regions showing significant group-by-task activation contrasts in the fMRI analysis), the authors observed lower synchrony in alcoholics versus control subjects between the PCC and middle cingulate cortex, which they interpreted as reflecting difficulty in adapting functional network activity to executive task demands.
Activation in left anterior VLPFC has been interpreted as evidence of the difficulty of retrieving and/or selecting between appropriate semantic features (Fletcher et al. 2000).
Although we did not define "ill" in the CII questionnaire, CII score predicted increased reporting of symptoms that we selected a priori as being reflective of sickness responses that manifest as "nonspecific" symptoms likely to be interpreted as "illness" (fatigue, drowsiness, difficulty concentrating, nausea, stomachache, body ache, and body temperature).
If a behavior feels identity-congruent, difficulty is interpreted as meaning that the behavior is important, not impossible, but what feels identity-congruent is context-dependent.
Moreover, the effect was present only when processing the participants' second language and it was interpreted as being related to the difficulty of the task and not in terms of motor simulation vs. no-simulation [61].
Firstly, sleeping difficulties, which were not interpreted as a symptom, per se, as the participants attributed their sleeping difficulties to their pain and other symptoms.
However, violence could also be interpreted as a function of underlying psychological difficulties.
