The phrase "ambiguous trial" is correct and usable in written English.
It can be used to describe a trial or experiment that has unclear or uncertain outcomes or results.
Example: "The researchers faced challenges in interpreting the data due to the ambiguous trial, leading to inconclusive findings."
Alternatives: "unclear experiment" or "vague trial".
PEs were generally larger for unambiguous than ambiguous trials (P = 0.03).
Therefore, it is only in ambiguous trials that the activity during the baseline has a significant impact on choice; in non-ambiguous trials, the responses to the sample diminishes any pre-existing bias in the neural responses (Serences & Boynton, 2007).
A separate ANOVA for ambiguous trials confirmed that PEs for the double-related condition were larger than PEs for each of the single-related trials (P < 0.005).
The performance on ambiguous test trials was computed based on the expected response as predicted by the new signal contingency during training.
" Examples for current use of biomarkers", above, and detailed in Table 3, a number of biomarkers have recently been identified to predict treatment outcome, and some have proven particularly effective in resolving unconvincing or ambiguous clinical trial results.
In relation to the use of reinforcement for the ambiguous probe trials, there are potential issues if the probe trials are repeated on more than one occasion.
In half of the trials, the pareidolia stimulus featured a picture of an object that had been visually degraded to make it ambiguous ("signal trials;" Fig. 2a).
Almost eight years after the attacks, Bush's Crusade is defined primarily through a set of ambiguous terrorism trials, such as that of Ali al-Marri.
There are also some caveats that exist with current methodologies which require further investigation, including the use of active choice versus go/no-go tasks, reward only outcomes versus reward and avoidance of punishment and whether ambiguous probe trials were reinforced versus non-reinforced.
